Float in hexadecimal.

• Hexadecimal string to Float

  Hello, I have a device that I am trying to contact using UDP. The device returns the data in hex strings, but I do not have very good documentation on the format of these strings. Here's what I have:

  00 - order type / BYTES

  01 - response Code / BYTES

  02 - task ID / BYTES

  03 - channel / BYTES

  04-07 - current PS / float

  08-11 - PS to courses / float

  12-15 - DAC voltage / float

  16-19-PS ripple current / float

  20-23 - PS common ground / float

  24-27 - temperature / float

  28-31 - PS Volts / float

  32-35 - Volt alternative channel / float

  An example of data return might look like this:

  C8:00:10:00:7F:8 d: f1:ba: ff: ed:22:39:f8: ff: 1f:41:4 c: 41:52:39: ff: 57:63:38:3d:f1:a7:42: ff: 35: be: 39:7f:49:a7:3 has

  The value that I really care about right now is the current PS in bytes 04-07. So, I did a 4 offset and a length of 4 on the subset of string which would be something like 7f8d f1ba. But I did have a success this turning point in a real number using the hexadecimal number VI to try every possible representation.

  Anyone have an idea how I can convert this? I added a screenshot of what I have now. Thanks in advance for any help.

  On edit, in which case it is useful a current of 1.00005 would return 96:01:80:3f or complete the answer incase I'm wrong offsets:

  C8:00:1F:00:96:01:80:3F:FF:57:63:38:C2:00:80:3F:EF:8 c: ed: 3A: ff: 57:02:38:0's: 25:c8:42:34:e3:7f:3e:bf:4f:88:ba

  Note: I'm assuming that you put into the colon for readability, and that you have not really found of the UDP.

  What you found actually is a string of bytes, not a string of characters that represents the hexadecimal values. In other words, you don't get the 'F' character to indicate a hexadecimal value of F. You get a byte of value 15 decimal places. In addition, the characters are in reverse order. To convert it, cut the section you want to reverse the string and then use the Cast of Type function:

  

• 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!

• Convert the hexadecimal string of Little Endian floating-point single precision

  I made a lot of tinkering and research, but despite all the very similar examples, I found, I think that I am limited by my lack of knowledge in programming. I gives me values such as 0000c 641 I need to convert to 41C60000 who must convert single precision IEEE754 to 24.75 as a standard 32-bit float. I saw very similar examples with boxing and unboxing conversions, but I simply can't understand it. Thank you.

  OK, so if you have actual letters coming, there are a few ways that you can do. You can basically change the string in order to get in order waiting for LabVIEW. Otherwise, you can do the same using data manipulation functions:

  

• Conversion to Hex string to a hexadecimal string that can be converted into a floating number with comma

  Hi, could someone help me please. I've been racking my brains out for almost three hours trying to solve this problem by trying different things.

  I have a code that retrieves a string of a robot control. The string is in hexadecimal and represents the number 1.234567. The string itself is 3FF3C0C9539B8887

  If I make a cast on the channel that I have, it simply returns the value zero.

  If I delete the control string, change it to hex and manually type in 3FF3C0C9539B8887 (so Labview auto updates 3FF3 539B 8887 C0C9) I get the result I need.

  However I can't find a way to do this. My apologies, someone out there is probably shaking he leads to something that is relatively simple, but I'm kinda new to deal with hex.

  Code is attached below in LV8 (although I'm under LV2012)

  Thank you

  The for loop is not necessary if you limit to 64-bit.

• Hexadecimal string to 32-bit float

  I get the data to the serial port as a string of bytes U8.

  I converts the string to a string of void who reads B 3, 43 CD7B, which corresponds to a value of 410.0. (Or in other words, this value should result in my conversion)

  I tried to feed the string above in a double game void. But the value reads as 3.27607E - 23.

  Any tips?

  
  

• Converts a string (float single precision) in decimal

  Hello

  I use reading series base and write vi to communicate with a device.  The answer I receive (shown in hexadecimal format) is 4606 8D3B, which from what I understand (this discussion: http://forums.ni.com/t5/LabVIEW/string-to-number-conversion-a-very-interesting-observation/m-p/32170... ) the data is not actually hexadecimal but rather binary and appears just hex for the user.

  My camera manual says that this information is "Float - 4-byte ANSII standard simple precision, low to high" and I'm trying to convert this string to a decimal value.  (it should be 0.004 or e-3 xx 4)  So far I've written a program that separates the bytes in a table of 4 bytes, each binary converts and then separate all binary bits and try to group return the binary bits in the exponent and the mantissa to calculate the value, but it seems rather convoluted and I hope that there is a more simple function in that all this is done automatically.  Also, since the answer is low to high, I understand that I must first return the number of 3B8D 0646 make high to low, but I think I did that already, it's just the conversion that I do not know how.

  Any help would be appreciated, thanks

• How do the math based on the hexadecimal display?

  I'm trying to convert a float for hex number, then get the sum of each byte. Please see attached photo, for example 30.5 converted to 403 8000 0000 0000 using hexadecimal display. I want to get the sum of each byte, 40 + how 3rd + 80 + 00 + 00 + 00 + 00 + 00, could I do in the labview.

  Any help will be greatly appreciated!

  I have not tried, but I think you can use "string to byte array", then Add the elements of the array.

  Hope this helps,

• Scan for float to string

  Hello

  I'm reading a float of 4 IEEE 754 bytes from a string (char array) using the scan function. I tried all kinds of setting shaped versions described in the help, but I can't get this good work. I get a string from a COM port. It looks like this in hexadecimal (the floating point number is between [brackets]):

  FF FF FF FF 86 1E 1A 6 82 22 01 07 00 00 11 [C0 52 8F 9F] DB FF...

  The format of the string is always like that. The first 15 bytes are some commands I want to jump and then I need to read bytes, 16, 17, 18 and 19. The result in this case should be - 3.290016.

  Here are the last of my many attempts to remove the float:

  buffer character [24];

  float myFloatVal = 0;

  ...

  Scan (buffer, "% 4f [i15b4]", & myFloatVal);

  This example returns '0' for myFloatVal.

  Any advice would be welcome!

  Frequency conversion seems a bit tough: while he plays well with double I'm not be able to make it work with floats too

  I can suggest possible workaround with sscanf:

  sscanf (buffer + 15, "%c %c %c %c", (char *) & myFloatVal + 3, (char *) & myFloatVal + 2, (char *) & myFloatVal + 1, (char *) & myFloatVal);

• Convert a single number to a hexadecimal string of 32-bit and exchange the high and low bytes

  I need to convert a number single precision floating decimal to hexadecimal format of 32 bits, share the high and low bytes and that convert a hexadecimal string.  I tried to use the 'Word of Swap' function but it seems to have no effect on the unique number.

  Then

  A single decimal number of entry: 100

  Convert 32 bit hexadecimal string with the low byte first: 0000 42 8

  Anyone have any ideas?

  Thank you

  Slightly lighter, try to cast U32 and exchange words. Same difference.

  (apparently, exchanging words is a NOOP for SGL, but still accepts SGL without constraint. Interesting...)

  

• Notes 'float on top' is always grayed out.

  Hello

  I used to be able to put a note on a separate window and then "float on top. However, since updating to OS X El Capitan 10.11.6, it has always been grayed out. Even on the full notes window, I can't make it float on top.

  Is this a bug? Is it just my macbook? Or is there a way I can get 'float' on top working again?

  Thank you.

  Patricia.

  Hi patsoup!

  I understand that you have a question about the feature 'float on top' of the Notes app, and I'm happy to help you. How the works seems to have changed.  Now, rather than tearing off a note to display it in a separate window, you can double-click the note entry in the list to the left of the application Notes. Once a note in its own separate window, the menu item 'Float on top' becomes accessible.

• How can I add text floating to a clip? (not a title, floating text that can be moved)

  How can I add floating text? Or is it possible to move the title autour text, how do I do?

  If you can not get the desired effect using the scrolling credits, the Far Far Away or the titles of Ticker,

  the only way that I can think is to create a file with the text you want on a green or blue (outside of iMovie) and put it above a green or blue background element in the timeline panel.  You can then use the image in the photo installation and creation of keyframes to move the text on the background.  See http://help.apple.com/imovie/mac/10.1/#/mova1aaa682b for more details.

  Share/export this file, then import the file and place it above your video clip.  This time, use the blue/green screen so that the text appears on top of your video.  See http://help.apple.com/imovie/mac/10.1/#/mov82da1338a for more details.

  Bulky, but should work.

• I can't delete a game called Float that gives the message waiting. The cross and the oscillation with delete option appear, but it won't when I select Remove. Any ideas please?

  I have a new mini iPad 4. I can't delete a game called Float that gives the message waiting. The cross and the oscillation with delete option appear, but it won't when I select Remove. I don't know how it came to be. Any ideas please? Thank you.

  First try a reset to see if it finishes downloading. Press and hold the home and power buttons until the Apple logo appears. Release the two buttons. Wait until the iPad tour starts on its own.

  Check if you can remove the application. If not go into settings > general > use iCloud and storage > storage > storage management. Wait for the list of apps to open. See if the float is on the list. If it is delete it from there.

• An easy way to remove floating ads when they appear (for example, not prevent it)?

  Usually I don't mind the ads on web pages. So, I feel strongly to use ad-blocking software to prevent any or all kinds of ads. But I don't mind the ads that float on web pages because they often block the view.

  Although some floating ads allow the user to close them, more pop ups or other types of malware, can appear after their closure.

  Yes, is there an easy way (an add-on, perhaps) to remove the floating ads after they appear and prevent them from generating more ads or to show again when the page is reloaded?

  Maybe something like "CTRL + Alt + left click on ' applied to the floating ads?

  I don't want to turn off scripts and Flash.

  There are Add-ons that, but they don't have not been updated in a long time, while they might have problems.
