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. Craig

Phobos has std.bigint, but the documentation recommends GMP for "very large numbers". http://dlang.org/phobos/std_bigint.html

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.
