Problem of float to multiply

Hi all

I had the problem, that's when I mulitiply float with float, I got the wrong result.

for example 0.01 * 27.0 = 0.26999998

the encoding is

float totalEmailPrince = (float) emailPrice * (float) totalEmailSize;

emailPrice is the float and totalEmailSize is of type int.

Help please!

Make your own class to represent a sum of money.

Store data as the sum of cents.

And do a Get accessor that gets this sum as formatting string instance.

To separate the amount of cents and dollars use % operator (mod), subtraction (-) operator.

For example:

581 cents,

581% 100 = 81

581 - 81 = 500

(int) (500 / 100) = 5

result: $5.81 (five $ 81 cents)

  • Problem with FLOAT and DIV widths

    I create a HTML page, and I would like to have three "modules" (for lack of a better word) along the bottom, each 180 pixels wide, containing textual information. I created my document like this:

    < div class = "module" >
    <!-here...-> content
    < / div >
    < div class = "module" >
    <!-here...-> content
    < / div >
    < div class = "module" >
    <!-here...-> content
    < / div >

    My CSS looks like this:

    Unit {}
    float: left;
    Width: 180px;
    margin: 15px;
    }

    .. Yet when I do this, the modules are stacked on each other rather than inline. After some research, it seems as if the "width" attribute that causes the problem. (If you look at This example- a similar situation - it works very well for them. They do not use a width attribute, but when I add a width attribute in their code, it breaks.)

    The confusion of mixture is that Dreamweaver 8 displays the page exactly as I want it in its internal browser, but Firefox and IE exhibit the problematic behavior, I have just described.

    Any ideas?

    Thank you.

    Thanks to everyone here who took some time to answer my question. Turns out I had a 'div tag "on the inside of each of my modules that launched off the coast of the layout, even if no style has been defined for this tag.

    I know it's something that could have been found easier had I simply posted the source code here... but the site I'm trying is confidential for my business, and I couldn't. Believe me, my first reaction was to do. However, your ideas certainly led me to the right solution. Thank you!

  • Satellite A300 - 08V PSAGCA - CPU multiplier fluctuating

    HI guys.

    Recently, I had a few problems of CPU speed with my Toshiba A300 PSAGCA O8V01N.
    At first I had no idea what was causing the problem, nor in how to identify it. I've recently went to a tech forum and asked the same problem for the guys out there. Thanks to them I found that my cpu multiplier changed automatically, apparently as a result of heat from the system.

    The previous forum that I have been about this problem.

    I thought I found a bios update patch. (Insyde h20: since version 1.60 to 2.10). Update the bios had temporarily solved the problem, putting up my multiplier back up to 9 and the 2.4 GHz complete I was supposed to be seen. However, when I played COD:MW2 afted address the issue of the frequency of the computer has really hot (fortunately I got off before it crashed).

    After that, he returned to .79Ghz at 3 x multiplier (as before). Before I finish, I looked in the bios for all parameters. Called the "dynamic CPU frequency Mode" was the dynamic value, which regulates the energy consumption and, consequently, the speed of the CPU.
    So I applied it to still weak. (which means that this feature is disabled.) However, it has not changed anything noticeable...

    Apart from that, there was no other parameters related to my problem. Can anyone help?
    Can I change the multiplier?

    Thanks in advance.

    + The message was edited: link has been removed - unauthorized +.

    Hello

    My knowledge, laptops BIOS does support all of the options that allows you to change the CPU multiplier.
    A few years ago, I used a desktop PC and BIOS and my taken desktop PC motherboard support this feature, and I was able to overclock my processor. But this is not possible with the BIOS of the laptop.

    If you want to set the CPU to lower the frequency then I recommend the settings in Vista or Win 7 Power Management.

    There is usually an option called CPU power management and you can set different performance (min and max) while the laptop is running on battery or power.

  • Blue Jay 22 is not floating with IE11

    Hi all

    I am using 4.2 Apex and created a tracker application using the Blue theme 22 'Jay.

    Our company uses IE9 and we have not had any problems of floating. We recently move to IE11 and now for most of our end users, they have to scroll left to right to see all the information.

    My guess is there must be some modifications to the HTML/CSS code... but that's where I'm lost would appreciate any help.

    I can see that Compatibility Mode is not (properly) enabled in the view of IE9. You can verify that it was somehow enabled for users involved in IE11?

    Except that I don't think there are many who can suggest without being able to get away with it.

    I had various problems with floating fields, mainly with extra spaces being placed before and after a currency field. For example, I had an extra space between the field and the punctuation immediately following floating.

    If you select the type of field as "Digital field" and then configures the model of what follows, it should help. Remember to remove the spaces before and after the field floating, as you add them to the model.

  • Test the analog inputs in a PCI-6013

    Hello. I m using a PCI-6013 OR DAQmx 9.1.1 with Labview 8.2 (sued) WinXP. The jury has undergone an immersion in water during a flood but was cleaned, recognized by WinXP and NIDAQmx.

    I have run the Measurement & Automation explore and use the test under option OR-6013 'Dev1' panels 'devices and Interfaces. Here, I can see that the digital and clock output work perfectly (I can change the State of the digital channels and duty cycle and frequency of the clock). The problem arises when you try to measure an analog voltage. I tried on several cases not all analog channels using NRSE and differential modes (switch accordingly connections).

    The signal comes from a (4 Hz, squares and sines, 5Vpp) signal generator via a CB-68LPR connector.

    I only see something comparable to the entrance of singal when you use differential inputs (signal connected by J57 and J23) AI7, but the signal I see comes with 100 mVpp instead of 5 Vpp (I can see changes in the shape, every time that I have spend of a sine, square, ramp...). I also tried connecting J23 AISENSE (J62) and AIGND (J67), to avoid the problems of floating source. The same thing happens when enter and set up the acquisition by the vicinity of data in the Explorer of Measurement & Automation. I m using the reach of the signal in the different ranges, tried with 04:55, -1 to + 1, 09:50... When you configure tasks NIDAQmx I choose to read different samples (100, 1000, 10000) rate (100 Hz, 1 kHz,...) and combinations. Anyway, the input signal is always 4 Hz. I checked the signal with an osciloscope and I see it perfectly.

    Is it possible to have the broken while the digital and general-purpose analog input clock outputs are OK? Y at - it a tip for the connections I should know about? Thanks in advance for any guidance!

  • CPU - bad slow BIOS settings

    I ran CUP - z on my m9660sc (9600t USA) and to my surprise I discovered the Core i7 920 CPU only run at 1600 MHz.

    Given the CPU is intended to be run to 2670 Mhz that I feel a little cheated, so I test the CPU at 100% charged and remains at 1600 MHz.

    I check the BIOS settings... Well good luck with that on a HP Hardly. everything you can change. I'm surpised that I was allowed to change the time...

    I know that the problem is that the multiplier is only set at 12, when he supposed to run at 20 x.

    Then what should I do to get what I paid?

    In Vista, make sure that you use the parameter profile of power is 'High Performance', is 'balanced' (Control Panel-> Power).  The power profile setting that locks the CPU at 1.66 Ghz on the m9600t is 'Power Saver'.

  • How to speed up composition when you work with files open exr?

    The main issue is covered by the title, but to help give you some background, here is a concise summary of my workflow:

    I hope someone can help.

    I produce 3d animations composited .exr files saved out of 3ds max with vray.

    I usually use separate .exr sequences for each of the items to make... rgb, reflections, the hardware ID etc... rather than recording a sequence unique .exr with all items incorporated in each frame.

    I do it for flexibility, but I'm open to the idea of using the second approach above - certainly easier search and replacement of files sequences fact.

    I find the somewhat slow Extractor plugin loading several exrs sequences and even a single sequence is so much slower that other files formats I can watch other floating point options.

    I tried the new cache for exr CC 2014 files options, but it is still slow.

    Files are stored on a single 2 TB internal sata hd drive but performance seems no different when the composition of a flash ssd drive internal or ssd in another pc on the network.

    Strangely, an external drive plugged into usb 2 or 3 seems faster, after several trials but way still slower than png, tiff etc...

    Any suggestions on improving my workflow for faster feedback from EI?

    Thank you very much

    I stuck with 16-bit when possible. This has the advantage that 3D programs themselves make a conversion to integer values, and there is so little about consistent across formats and applications based on standardized assumptions like that and space sRGB and Gamma. 16 bit TIFF is quite powerful in AE. Problems with float TIFF and HDR files are pretty well planned, because all I know is no interval of fixed value defined in the file format specifications and everyone uses their own mishmash. Inevitably, you can't completely eliminate EXR, but you can book it for things you actually need as usual or motion vector passes. in my workflow certainly hacky inflate a 16-bit to 32-bit file never made much of a difference of 32-bit native files, but of course you can use subtly lit scenes al lthe night where it could be more relevant than for my reasonably evenly lit technical visualizations and motion graphics all...

  • SDO_ORDINATE_ARRAY precision control

    Dear all,

    Greetings.

    Hello.

    I met a problem dealing with storing the geometry with correct values SDO_ORDINATES accuracy. When I download the geometries in Oracle, I had chosen FME (software does convert and automatically download data.) BUT when I export the ordinates of geometry to the other calculations or analysis programs, I found the details for each point of contact information is too many (I really useless that much, in addition, he has problems for floating numbers calculations.) For example, the lat/long value would be 10.0000000000000001 / 20.0000000000.

    In the other program, I cut the data without these numbers a lot, but I also need to refer to the database, and there are already some lost data. I would like to have the data cut into the database once I have download the data in oracle. I can't find a feature or command so far, / of the FME or the documents of the oracle. Everyone knew this, please leave me your comments. Thanks in advance.

    You can do it in FME using the [CoordinateRounder | http://docs.safe.com/fme/html/Transformers/content/transformers/coordinaterounder.htm] transformer.

  • T500 P8600 (2.40 Ghz) Core speed problems - works only in 1, 6 GHz (6 x multiplier)?

    Hello

    I'm new here and I hope you can help!

    System specs

    Lenovo T500 (2081-CTO)

    CPU: Intel Mobile Core 2 Duo P8600 2.40 GHz

    RAM: 6 GB DDR3 PC3-8500 (2 GB + 4 GB Hynix halogen)

    BIOS Lenovo: 3.13 - 1.06 (March 2010)

    Operating systems: Windows 7, 64 bit

    Battery: Yes

    Power: 90W installed

    Power setting: maximum performance; Max CPU speed: more top [ThinkVantage Power Manager 3.12]

    Setting BIOS: Intel SpeedStep disabled; Everest EU 5.50 confirms: C1E & EIST are both: "supported, disabled.

    All Lenovo drivers are up to date *.

    ---

    Problem: Base speed is blocked at 1.6Ghz (multiplier x 6.0) and only fluctuates several Mhz from time to time. I think it should be fixed at 2.40 Ghz, I have disabled all the settings save CPU speed.

    Basic speed (1.60 Ghz) conforms to:

    -Everest Ultimate Edition 5.50

    -CPU - Z 64 bit 1.54

    -Intel Processor Identification Utility 4.22.20100224

    All of these are the @2 P9800. 40 Ghz is clocked at 1.6 Ghz or 1.59 Ghz.

    I ran the load/stress test, Super-Pi etc... and obsevered the basic speed - it never changes or is greater than 1.6 Ghz.

    Super Pi takes 31 seconds, where landmarks on a normal P8600 2.40 Ghz see the this should be done in 20 years.

    I have read several threads in these forums and tried all the things suggested:

    Example of Lenovo Forum Thread 1

    Example of Lenovo Forum Thread 2

    I even tried affecting performance Max CPU speed to "Adaptive", and yet, it does not go beyond 1.6 Ghz.

    Can anyone suggest other things I can do to make sure that it is not a problem? I thought I bought a 2.40 GHz, not a 1.6 Ghz.

    I have several more months remaining warranty, contact Lenovo to return my CPU? or is it a fault in Lenovo BIOS?

    Intel speed step must be enabled.  If you read what it says in the bios, if it is off then they processor will not let the State of the minimum speed.  This is the case on my T510.

    Give it a try.
