Double to hex

[Mourad]

Hi all,

Need little help about converting double number to hex for example; need to convert -0,35 and +0,35 to hex. Any ideas?

There's an App VI for that

EDIT:

Forgive me for being an idiot, I forgot some places use commas how I use decimals

Try scaling your number by say, 100 (if you want two decimal places) and then doing two individual conversions to hex. Sadly I think you might have to do the sign with an additional operation/comparison.

Additionally, if you want the raw hex from the number encoded as floating point, you can type cast it to a similarly wide data type (like U64) and do the conversion to hex using that number.

Strictly speaking you can't do what you are asking. A pure hexadecimal number is an integral value and cannot represent a fractional value. You can get the hex representation for the binary value of the double value but without knowing the internal representation of the value in terms of the mantissa and the exponent the hex value is rather meaningless.
