Hello, I'm interested in the library you use for calculation. Is it good cross platform compatible. Can it handle fractions? I'm asking because currently I'm using C++ standard data types and boost complex in my calculator (PhyxCalc) and I want to add arbitrary precision, but GMP and CLN are not very Windows (and Symbian) compatible.

It also looks well-tested and cross-platform; at least I was able to compile it without problems for Windows, Linux and Windows Mobile 6. I don't know about Symbian, but it seems to only require a sane C compiler.

That sounds great. How is the performance on mobile devices?

I didn't notice any performance problems, but I had only tried it on simple formulas with a few operations.

Hello! Yes, decNumber implements all basic mathematical operations (+, -, *, /, %, power, bitwise operations) and some functions (abs, sqrt, exp, ln...).

You can look at /src/engine/BigDecimal class in MaxCalc - it is a C++ wrapper around decNumber which implements a lot of functions and operations.
