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. |
