Conversion Decimal Number to 32 bit floating point

[groegler]

In order to write to a register in a digital camera, I need to do a conversion from a decimal number to the IEEE-754 single precision 32-bit representation of this number (and also the other way around).

Does there exist a vi, which does that? Or maybe a Matlab routine?

Yes, Mantissa & Exponent vi.

[groegler]

That is not what I'm looking for. I do not need to know how the number is written in binary notation (which is what mantiss and exponent basically does) but how it is written as a 32-bit floating point number.

[Xu]

"Decimal String To Number" vi
or
"To Single Precision Float" vi ?

This should do it...

Yes!
This works, if you set "Type" to "09" for single and for the output you select a number in I32 binary reprensentation.

Thanks a lot.
