Nice - but like my perl solution and bob's windows solution, it doesn't deal
with fractions (I know, I know, I never mentioned that - sorry).

Actually I got mine to deal with simple fractions, such as 0.5 and 0.25 etc. and
I THINK I now know how to deal with more fiddly ones. I think I keep doubling it
until the fractional part is either negligble in comparison to the integer part,
or until it disappears...

That sounds like a working strategy.


But maybe this page does what you need ?

http://babbage.cs.qc.edu/courses/cs341/IEEE-754.html

"IEEE-754 Floating-Point Conversion
From Decimal Floating-Point
To 32-bit and 64-bit Hexadecimal Representations
Along with Their Binary Equivalents"
