hex to float conversion

[Paul]

I have a hex number that I need to convert to a 32 bit float

eg 0x44361000 => 728.25 (from
http://sandbox.mc.edu/~bennet/cs110/flt/ftod.html)

Ive written some ugly code to do it, but Im sure there must be a nicer
way with pack/unpack/sprintf

I also need to go from floats to Hex too

Can any one help?

0x44361000 => 728.25

I'm not sure about the various sign-bit issues, but something like:

hex = 0x44361000
p [ hex ].pack("I").unpack("f")[0]

Might get you started.


Cheers
