Hi.

Do you know any library with high-precision doubles? I need at least 20-30 decimal digits without rounding, it will be better to have 50-100 decimal digits.

Thanks.

This isn't a D library, but GMP might fit your needs:

http://gmplib.org/

It is in C, so you should be able to interface with D code.

Phobos has std.bigint, but the documentation recommends GMP for "very large numbers".

No, I need double, not integer, so I can't use std.bigint.
I must provide at least 20-30 decimal digits without rounding after a decimal point.

Thanks.

Anybody knows a D interface for the GMP library? I can't find it at the Deimos.
