Re^2: HEX to floating point

I realize those subs contain a trivial amount of code but a packtard like me sure wouldn't mind seeing those gathered together in a module with a nice side of Pod. (Think of the fame, wealth, and women that could be yours!)

Sadly they are not portable due to the endianness of the source data and then the endianness of the destination reader system. You can find 3 diffferent ways to unpack hex strings in faq4 from memory (using hex, pack/unpack, and Bit::Vector]) As you may have noted BrowserUk presented a method that converts the data given from the OPs system (big endian) to his system (little endian wintel). When the OP tried to run it he found it broken. Pack/Unpack Tutorial (aka How the System Stores Data) by pfaut is an excellent resource for understanding pack/unpack.	[reply]
