Oli,
LabVIEW stores value in IEEE. But 4 bytes is a single precision float.
Just type cast your 4 bytes to SGL type. If it's not the value that you
expect, try to swap bytes and words to see if your value is big/little
endian bytes oprder. If not, send to me your bytes and number you want
to see. Rarely need to convert bytes to IEEE format programmatically,
but possible.
