• 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

• Converting varchar2 to float

  Hello community,

  I have 2 columns with as many lines of type varchar2 attributes and I intend to convert to float. Seaweed can you tell me what the best way to do it and how?

  Best regards

  NLS_NUMERIC_CHARACTERS is normally set ".,"allowing both"."and ",    However, any non-digit character (for example, a letter or a symbol) present in the column in any row would cause an error ORA-01722.  So you need to check the data that are stored and clean.

• serializeJSON is converting ints to floats

  CF10 updated 11 Win7 x 64

  I'm running on a problem that I just noticed with serializeJSON()... ints are converted to floats. Here is the code:

  < cfset r = {}

  « x » : 0,

  'y': 1

  } >

  < cfoutput > < pre > #serializeJSON (r) # < / pre > < / cfoutput >

  < cfset r.x = int (Val ("1")) >

  < cfset r.y = ceiling(100/10) >

  < cfoutput > < pre > #serializeJSON (r) # < / pre > < / cfoutput >

  Here is the result:

  {« y » : 1, « x » : 0}

  {: 10.0 'y', 'x':1.0}}

  Is this messed up or what?

  Also discovered that a simple addition operation creates a float:

  Release 3.0

  Workaround solution:

• Convert unsigned bytes (U8) timestamp date.

  Leave a device of the CAN, I the date and time in the form of a series of unsigned bytes seven (U8) as follows:

  Example of century 20

  Example of year 10

  Example of month 4

  Example of day 26

  Example hours 20 (20:00)

  Example of min 20

  S example 1

  that would be:

  26/04/2010

  20:20:1

  What is the best approach for convertng these seven values in a DateTime format only to display purposes?

  Thank you.

  Chuck,

  Here are some ways to do it, but of course there are others.

  The first for the digital inputs or concatenate a string with the second.

  

  Hope that one of them is what you need.

  * Edit - added combining or century & year

• 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

• Conversion of 16-bit unsigned 32-bit float

  Hi, I'm new to labview and data types in the electronics. Due to a shortage of labour in my company, I am required to do it myself. I've been through several labview basic tutorials and examples, but I am unable to do anything properly with labview. Any help is very appreciated.

  I'm using labview 8.6.1 and I downloaded the drivers for modbus. Currently, I am required to read data out of a sensor and write the data to a file. Using the ".vi MB series Master query Read Input registers (poly)", I am able to read the data in the registers. However, the data in the registers are 16-bit unsigned and does not give the "real" value I'm not sure about this, but I tried to use simply Modbus 6.3.6 and change the bit 16 32-bit unsigned type float makes the job of showing the real value.

  So, my question is, how do I get the actual values of the VI? I apologize if this is a simple question but I am new to this and don't have the time to study further in this regard. In addition, I apologize in advance if not enough information is given. Her updated the VI of "Master Series MB query Read Input registers (poly) .vi" that I used to write data to the file, as well as 1 text files, I got is attached.

  Thank you for your help and sorry for any trouble.

  Here's my VI registered under LV8.6.

  You have pretty cables through your VI, but it is ridiculously little handy, easily scalable and uses some Rube Goldberg constructions.

  Your Rubes:

  1. table to the cluster to unbundle converty.  Then grouping to a cluster and then to a table.  No need to go through the songs and dances of cluster.  You could have used the Index table and table build and not had to convert anything to a cluster or backward.

  2. using a constant Dbl to change than one through the digital conversion function to determine the data type for the type cast.  Eliminating the conversion and has created the representation of the single precision instead of double precision constant.

  3 code dozens of times when he should have been treated in a loop of duplication.

  If you use me as a Subvi, your screen real estate will be less than a 1/4 of what it is now.

  You say you want to read a bunch of records that are not adjacent to each other?  You can make several requests of reading.  Write a query command, then read the answer.  Then write another order of demand for various registers and read this response.  It depends on how different readings, you do or how far records of interest are about whether it makes sense.  If you need read a two pairs of registers, which are some distance apart, it might be more efficient to perform a single read multiple registers if they are close together and just throw the records don't care you.  It will be more bytes to read at the back, but it might be faster because it can be done in only one reading.  Or you could do two readings targeting your specific records.  It might be less bytes to read in each message, but it will take more time to make two requests to read and wait for responses between the two.

  I don't know if the limit of 125 records is something to make your device, modbus or modbus in general protocol library.  I want to say that it might be that the modbus Protocol usually means that records the 125 250 bytes of data.  Factor of a few bytes of the command of the response and the checksum, you will be 256 bytes.  Modbus packages are designed to take less than 256 bytes so that only a single byte is needed to tell how many bytes of data will be forthcoming in response to the message.

  With selective targeting of your records to read and using the table of Index to read specific float32 values of interest, you can write the 12 values you want in the file instead of all those you don't need.

  Which data fields are defined as floating point?

• Can anything convert ALAC 24-bit or higher?

  Personally, I would like to convert it to a minimum of 32-bit floating-point ALAC, but I'd settle for 24-bit integer. 16-bit is too. I heard that the ALAC has the ability to support 384 kHz, 32-bit floating point, maybe even 64-bit Floating Point (IEEE) the way WAV files can.

  Can not export or convert to 32-bit ALAC with a minimum of 44.1 kHz and 256 Kbps?

  SteveG (AudioMasters) thanks for the recommendation of Foobar2000, but it seems sketchy. Whatever it is, I did a short study in order to determine which program should provide the best quality of conversion ALAC as well as inadvertently determine best quality (in my opinion) output formats:

  Surprisingly (not really), iTunes is the best converter ALAC (free), may be replaced by Logic Pro X, nothing else. It is possible to convert to 32-bit Float ALAC, 192 kHz and maybe even of 384 kHz, but not unless the source file is already 384 kHz. For 32-bit conversion, the source must be exported from Adobe Audition (CS6 or above I think) as 32-bit integer. In iTunes, it converts the floating-point format. 44.1 kHz being more than substantial, a float of 32 bit 44.1 kHz ALAC equals perfect compressed lossless Apple available.

  Furthermore, I have determined that supplied iTunes perfect conversion of any waveform is registration, although ALAC iTunes conversions, as well as others, perhaps, reduce the peaks that exceed the threshold, but convert otherwise perfectly. without zooming on the threshold, you would never know there was a difference. This is recommended only with files that have reduced overall gain or who have already had dynamic range compression or fixed limitation.

  Better yet, Adobe Audition can export files of Point floating (IEEE) FLAC 32 bits with original sampling frequencies (so you can resume 44.1 kHz) for perfect conversion, and I mean perfect. I checked the sections that were exact matches as far down as 1 hudred-millionieme of a second.

  Perfect lossless Compression: Minimum 44.1 kHz, 32-bit floating point (IEEE), FLAC

  I edit in WAV format, export WAV to Apple to convert to the ALAC, FLAC WAV export and destroy all WAV, FLAC become my source. The routine is perfect for me.

  I can share my pages of notes of my studies over the past two weeks to determine all the data and the conclusions that I have collected with anyone.

• How to convert the string to a full decimal point and left shift

  Hey guys I tried to convert gps string to an integer, like this

  A string that is 2467.8976 and I need to convert it to a similar integer as point of this 2467.8979 so that I can shift the decimal point to the left (24.678979) which i coudnt do it with the chain. It's just been my 2 weeks with the labview so be gentle. Thank you

  Hi Awais07,

  Once you have created an indicator that signals the output of parsing the string, right-click on this indicator > display... Format > increase the value of the digit 9

• Reading logs float Modbus RTU

  I'm having a problem with loan any floating point number correctly in the distance a 100 Power Meter shark.

  I can read sucessifully a block of records containing the name of meter and the serial number as a 16-bit characters.

  For example when I read records 1-16 on the map and flatten them into a string, I get a string of work completely returned.

  

  When I try and holding registers A 1012-1013 (AMPS) I get really funny to read numbers when I converted to a float.

  Here is my code so far

  

  With my front panel settings:

  

  Expected value, I'm looking to have returned: 11.11 amps

  but

  When I use an indicator to read registers: 19265, 0

  Same value when I do a conversion

  When I do a type cast to a float: 1.26484E + 7

  I tried some different combinations such that read that a single register and join the numbers, both in order to big-endian and little-endian, still no luck.

  Help, please!

  Here's the modbus float definition according to the owner's Manual:

  

  Also, I saw that the Toolbox Modbus has sometimes behaving strangely of the off-by-one-register (so you need to actually ask a different address to get the desired data) and that some devices have a behavior even more strange out-of-one byte, while now you're out of half of a register, and you will need to ask for more records and then reorganize the bytes by taking a byte of the previous register or end.
