Double precision maths library

Unfortunately, we need a range which includes numbers from 0.0005--- to 16,000,000^3 both positive and negative. We have looked into using 64bit integers but this requires an aweful lot of extra scaling which we feel would be easier to achieved in fp.

how lovely

achieved in fp
is that "fixed point" or "floating point"

ambigous abbreviations hurt when you sit down.

I'd always assumed fp meant 'Floating Point' and nothing else!

And post by the assupmption that someone reading this in Farawyistan makes the same assumption.

We seem to have lost the thread!
Double precision maths for the 8051 - any ideas?

"Double precision maths for the 8051 - any ideas?"

I thought you had it when you said, "Many thanks Graham. That will do nicely with some slight modifications." in your previous thread?!

I really feel for you.
you may actually have to work to get what you need. How horrible
