library for arbitrary-precision floating-point arithmetic (Python3)

Mpmath is a pure-Python library for multiprecision floating-point arithmetic. It provides an extensive set of transcendental functions, unlimited exponent sizes, complex numbers, interval arithmetic, numerical integration and differentiation, root-finding, linear algebra, and much more. Almost any calculation can be performed just as well at 10-digit or 1000-digit precision, and in many cases mpmath implements asymptotically fast algorithms that scale well for extremely high precision work.

If available, mpmath will (optionally) use gmpy to speed up high precision operations. If matplotlib is available, mpmath also provides a convenient plotting interface.

Its features include:

  * Fair performance -- typically 10-100x faster than Python's
    decimal library
  * Transcendental functions -- all functions from Python's math and
    cmath modules, plus a few more like gamma, factorial, erf
  * Complex numbers -- with support for transcendental functions
  * Directed rounding -- floor, ceiling, down, up, half-down,
    half-up, half-even
  * Unlimited exponents -- no overflow or underflow

This package contains the Python 3 version of mpmath.
