%global _description %{expand:
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.}
