The bigfloat module is a Python wrapper for the MPFR library for
|
|
arbitrary precision floating-point reliable arithmetic.
|
|
|
|
The MPFR library is a well-known portable C library for
|
|
arbitrary-precision arithmetic on floating-point numbers. It provides
|
|
precise control over precisions and rounding modes and gives
|
|
correctly-rounded reproducible platform-independent results.
|
|
|
|
The bigfloat module aims to provide a convenient and friendly Python
|
|
interface to the operations and functions provided by the MPFR library.
|
|
The main class, BigFloat, gives an immutable multiple-precision
|
|
floating-point type that can be freely mixed with Python integers and
|
|
floats. The Context class, when used in conjunction with Pythons with
|
|
statement, gives a simple way of controlling precisions and rounding
|
|
modes. Additional module-level functions provide various standard
|
|
mathematical operations. There is full support for IEEE 754 signed
|
|
zeros, nans, infinities and subnormals.
