%global _description\
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.
