# PyMPF
This is an arbitrary precision IEEE-754 floating point implementation.

The main motivation is correctness and test-case generation, so a
number of things might seem a bit strange. This library has a bunch of
limitations and should never be used if you want things to be
fast. [MPFR](https://www.mpfr.org/),
[SoftFloat](https://www.jhauser.us/arithmetic/SoftFloat.html), or
[SymFPU](https://github.com/martin-cs/symfpu) is what you want.

Why "yet another" implementation?
  - This library supports RNA (MPFR does not)
  - This library supports subnormals and infinities (MPFR does, but only with
    tricks)
  - This library uses IEEE or SMTLIB terminology where possible (MPFR tends to
    stick to more "maths" terminology)
  - This library is implemented completely in Python unlike gmpy, mpmath, etc.
  - This library is an independent implementation so can be used to check
    Z3/SymFPU
  - This library uses a stupid but simple algorithm to do rounding

The main use of this library is random test-case generation for
SMT-LIB. It has been used to validate the FP implementations of CVC4,
CVC5, Z3, MathSAT, BitWuzla, SONOLAR, Alt-Ergo, Colibri, goSAT, and
xsat; and has found bugs in all of them ;)

# SMT-LIB random testcase generator

# Requirements
Python 3.8 or later.

# Documentation
This is very much work in progress and entirely incomplete (I just
started adding this).
