Double precision maths library

Hello Paul
Many thanks for the offer and I would welcome a copy when you get it all sorted. We are doing polynomial calculations linearising a 24 bit sensor input on some micro balances (scale). Speed is a secondary requirement, well, no requirement at all really, the most important thing is accuracy.
best regards
Dave

Hello David

If you send me your contact details (to paul.bramley@metrosol-ltd.co.uk), I will get in touch & send you the results of my efforts.

We are doing polynomial calculations linearising a 24 bit sensor input on some micro balances (scale).

Have you considered (and discarded) other approaches for doing this (e.g. lookup-table with interpolation) ?

We have considered using interpolation and thats the way we are now doing it. We have succeeded in using 64bit integer maths with that so there is no need to go to f.p.
