• Will I lose data conversion to double precision single-precision float?

  Before you say Yes...

  I use a crio unit in scan mode interface. Which returns the mode of scanning values in floating point double precision. Apparently I'm supposed to be able to choose between double precision fixed-point ("not calibrated") and ("calibrated") floating point data, but this feature seems to be exclusive to the fpga interface and is not available with the scan engine. The two data types are 64 bits per value, when it comes to the size on disk, anyway is still basically the same.

  The system continuously records 13 channels of comma floating double-precision at 200 Hz. using the binary file write, I measured it is about 92 MB/hr on the disk. (more than 120 MB/hr with PDM and much more to write on the worksheet) In short, this 92 mb/hr rate is just too much data on the disk on this system.

  The modules that I record since, 9236 9237 and 9215 c-series modules, have 24-bit a/d converters or less. Does this mean that I have not need 64-bit to represent the number and accuracy even?

  Can I force/cast point values double-precision floating that I receive of the variables of e/s scan engine to the data type of a different, smaller, as a single-precision floating point and retain the same precision?

  You can test it by looking at the difference between a DBL and converted to SGL DBL. But I support the Nickerbocker trick. I don't think it will make the difference

  Update all drivers, System Restore

  Toshiba help line after all the efforts suggest all reinstall them it is aggressive for me, because he would lose some software on the laptop that I had to transfer old PCs and had to plead with some software companies to transfer (as a single license etc.).

  If someone else has had this problem and is there a simple solution

  Will be

  Hmm, you could remove the software of the webcam of the system and could remove too the webcam from the Device Manager.
  Then you could clean the operating system using the CCLeaner

  This software is free and it can clean the registry and the system. I use it very often.
  Then restart the laptop and try to reinstall the software of webcam again.

  Good luck

• Error: Software of "Operation not valid Floating Point" as he tried to run Iolo drive scrubber

  Original title: cannot run A clean product Up

  I ran Drive Scrubber from Iolo now for 2 consecutive years. Now when I try to run it, it gives me an error message that says "invalid Floating Point Operation". I don't have any idea what it is. What is and how to clear up?

  Since this is a 3rd party software with which I am not familiar and the manufacturer of the product is not able to help you, I suggest you go back to a system restore point to before you have experienced a problem with the Drive scrubber the Iolo software.

• floating point No. the chain with the same precision

  I use "format string" to convert floating point No. to a string. Most of the numbers have a single decimal digit, so I use '%^0.1f' in the format in the connection string. But for our whole. like 150, it gets converted to 150,0. I want to avoid this, such that the chain looks exactly like the No.... What should I change?

  Use %#0.1f as your format string.

  Read the help file on the format codes.  The sign # told him to truncate the zeros.

• Convert c# to Java code - Floating Point Arithmetic

  Convert c# to Java code - Floating Point Arithmetic
  
  Hello
  I need to write a c# equivalent in java code. The c# code includes functions perform mathematical calculations. The result of these functions must match exactly with the c# (especially precision) counterpart. Here's a function that requires an equivalent java
  
  Public Shared Function squareroot (string n1)
  {
  If ((n1 == null) |) (System.Convert.ToDouble (N1) < 0))
  {return null ;}
  else {}
  return (Math.Sqrt (System.Convert.ToDouble (n1))) System.Convert.ToDecimal. ToString();
  }
  }
  
  C# two data types - float (32-bit) and double (64-bit) floating-point. It also includes a more specific data type float called decimal (128-bit). The float and double are supposed to follow the standard IEEE 754 floating point standard, but precise figures are different. Double c# has 15-16 digits for precision while the equivalent of java has 53, right? (the IEEE standard reference).
  
  Does anyone have an idea on what java equivalent data types/libraries must be used such that the results correspond with double c# and decimal?
  
  Thank you & happy new year

  This has nothing to do with the IEEE 754 standard, because nothing in IEEE 754 specifies how many decimal places should be used when a value is converted to a string. Simply because the resolution is between 15 and 16 decimal places does not mean that there is always an exact representation of any number of IEEE 754 format to 16 decimal places. In your example, Java chooses to create two decimal places more than c# don't but I bet that this is not a general rule you can count!

  The whole concept of using strings to represent the number seems to be skewed. I don't really see the point. It is mind bogglingly slow and in my view it does nothing for you. You have not yet met the real problem yet! What happens when Java or c# decides to use scientific notation?

  In your situation I would like to change the program c# use 'double' rather than 'chain', then you would find that you get an almost perfect match to all time. I make this recommendation of much written spending year of algorithms in C, C++, c# and Java of signal processing.

• Determine if an integer is a floating-point number

  I want to create a program that when an integer is entered in the digital constant, a floating-point number with zeros to the right of the decimal point lights up the LED on the front panel. The LED remains off for any other floating-point number. I know I want to use a ride to the nearest function, but don't know where to go from there.

  You want to say CONTROL, right?

  You just need a type of rounding.  No matter if round you upwards or downwards.  If you just around and then compare the entry to the rounded value.  If they are equal, you turn on your LED.  So all you need is a digital control, 2 functions, and a boolean flag.

• compare arrays of floating point

  Hi all

  I have a table of 2_D as

  1 0,0119

  2 0.0140

  3 0.0157

  up to 50 items.

  and the second picture is as

  0.0137

  0,0153

  0.0156

  up to 20 items.

  I need to compare second table with the second column that is the first table floating-point numbers . Find 20 items in table 1 that are as close as possible (maybe not exactly equal) to the 20 items listed in table 2.

  and return the corresponding values for the colors n ° 1 in table 1.

  ex. - 0.0137 will be compared with the entire table 2.

  He'll find 0.0140 and we get part 2.

  0,0153 next will be compared and so on.

  Final result will be a 1 d array with values of col 1 only.

  Help, please.

  It is confusing that name you the 2D file P1.txt and the 1 d P2.txt file.

  It seems simpler to use "worksheet file read" to read the two files.

  The mistake you make now is to create the table 1 d with the default tab as the delimiter. He reads only one, because there is no tabs in the file. All you need to is change the newline delimiter. It is what it is!

  

  Now, it seems to work perfectly, please test.

• BUG: Large floating point numbers convert the wrong integer

  Hello

  When you use the 'balls' conversion to convert integers to SGL, DBL and EXT there are certain values that convert evil. An example is the 9223370937343148030 integer that can be represented exactly as a SGL (and therefore exactly as DBL and EXT as well). If you convert this I64 you get 9223370937343148032 instead, even if the correct integer is in the range of an I64. There are many cases similar, all (I noticed) at the wide end of the ranges.

  It has nothing to with the integers can be represented exactly as a floating point value or not. This is a bug of authentic conversion you mind.

  See you soon,.

  Steen

  Hi Steen,

  Thanks for this identification. I confirmed the EXT to U64 conversion problem in simply trying to make a round trip on a xFFFFFFFFFFFFF9B0 of value U64 EXT and back, is xFFFFFFFFFFFFFFFF as well (and the intermediate value in EXT is correct).

  The problem seems to be limited to integer values with the upper part of 53 bits set, as well as all of one or more of the 11 lowest.

  I have reported this (#396305), as well as the limited display accuracy questions (#396337).

• Decimal in Floating point with cookers

  Hello

  I am wanting to convert a decimal value to be implemented at the scale of a floating point value.

  For example.

  a decimal value from 0 to 20000 where half is considered to be the zero point. Then share values and on the other of this average value are considered postivie or double negative (0-10000 considered negative, 10001 to 20000 considered as positive). Then, the resolution of each decimal value is compared to a predefined scale.

  Don't know how to do in this regard.

  Any help is much appreciated.

  Hello

  I hope I got everything you wanted.

  Please take a look at the attachment.

• floating point to hexadecimal string

  Hello

  Is attached a screenshot of what I'm trying to do.

  The equation that I in the formula box basically is supposed to enter a number between 30 and 100 (which represents the intensity percentage) and he will give a value in which when converted to the spell and fed in my instrument will give the corresponding intensity in floating-point (ie. 30% if I had entered 30 as my x in the formula) I need. Thus, for example my lowest intensity (30) would give me a decimal value of 239 of the formula which is "EF" in hexadecimal.

  This code does not work for some reason any. If I replace my conversion function of formula and hexadecimal, with only a simple chain control and display of spell and EF entry switch and feed it into the instrument intensity makes the adjustment to 30%! But I prefer to use the scale bar instead which does not... Can someone please tell me if my conversion function is messed up or something.

  Thank you!

  Try this.

• Version of the C API for LabVIEW FPGA 2011

  What is the version of the C API that will work with LabVIEW FPGA 2011?

  I guess as this one: http://www.ni.com/download/fpga-interface-c-api-2.0/2616/en/

  Version numbers seem to start by 2012 years.  It's the latest version I could find before 2012 and he was released in August 2011.  This time coincides with the annual festivities of the NOR week where a large part of the software/hardware is released.  It's a small download, so it shouldn't be difficult to download it and try it.

  But, you'll still need LabVIEW FPGA development according to this white paper: http://www.ni.com/white-paper/9036/en/
