How To Install python-mpmath on Ubuntu 18.04

In this tutorial we learn how to install python-mpmath on Ubuntu 18.04. python-mpmath is library for arbitrary-precision floating-point arithmetic

Introduction

In this tutorial we learn how to install python-mpmath on Ubuntu 18.04.

What is python-mpmath

python-mpmath is:

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

There are three methods to install python-mpmath on Ubuntu 18.04. We can use apt-get, apt and aptitude. In the following sections we will describe each method. You can choose one of them.

Install python-mpmath Using apt-get
