python/*: Moved a lot of Python stuff here

The criteria for whether something "belongs" in Development or
Libraries or Python or ... is admittedly arbitrary. As a general
rule, if it could be either Libraries or Python, it's Python.
Otherwise, pick one and we'll go from there...

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. |
