问题
I'm in need of floating point calculations for C# that can correctly store up to maybe 500 digits/decimals. Is there any built-in-type for this, do I have to create it myself, any library available or what is the best way to go?
Thanks
回答1:
MPIR, a fork of the GMP project, has C# bindings. Personally, I've found them easier to deal with when raising problems, to the point that I no longer worry about GMP (primarily due to its tendency to exit violently when running out of memory).
There are others listed here but I have no direct experience with them so can't comment on their usefulness.
回答2:
Another alternative that is more liberally licensed than MPIR is the BigInteger class available in the source code for the Bouncycastle C# library.
