dashu-float 0.6.0-rc.4

Arbitrary-precision float math library for Rust with arbitrary base and arbitrary rounding mode. Provides FBig, DBig, and CachedFBig with efficient base conversion, the hexadecimal float format used by C++ programs, and parsing and formatting in base 2-36. Transcendentals (exp, ln, trig, hyperbolic, powers, roots, pi) are correctly rounded; optional serde, rand, num-traits, rkyv, and zeroize.
