ieee32 to LV float

[RSibagatullin]

Hi,
I have an array of 100 bytes in Labview.Each 4 bytes  represents an IEEE32 float number.  Before I transfer  each 4 bytes to lavbiew float I was told that I need to reverse each  4 byte vector. Could someone show how do I get from this byte array a valid Labview float  type array so I can plot it? Thanks.

First you need to typecast the 100bytes to an array of SGL (assuming it is big endian), then convert it to DBL using "toDBL". You can also plot the SGL directly, so you don't really need the last step.

Attach a VI containing some real data (100bytes) as a diagram constant so we can make a small demo.

altenbach,
Thanks for response I don't have a sample data  at this point because I gather data from a UPD source  and this source is off for now.   But I have prototyped this  VI which I believe is  wrong  because it is very different from what you described.   I believe any 100 byte array will be ok for testing purposes.  Thanks.

I have wrote a subVI which uses some ideas from altenbach.  Please let me know what you think.  All I do is invert each 4 byte and then cast it into single precision.  Thanks.

OK, so you have little-endian data...

It is not clear why you are using byte arrays as inputs, becauser from UDP you get a string and it is probably more reasonable to work with strings directly. It's the same data.

Unflatten from string has endian conversion built-in, so that's all you need.
