Need arbitrary precision arithmetic in C #

Question

I need floating point calculations for C # that can correctly store up to 500 digits / decimals. Is there any built-in type for this, should I create it myself, any available library, or a better way?

thank

Answer 1

MPIR , the fork of the GMP project, has C # bindings. Personally, it’s easier for me to deal with them when I raise problems, to such an extent that I no longer worry about GMP (mainly because of its tendency to furiously exit with out of memory).
