Module documentation for 0.1.3.0

Arbitrary-precision dyadic numbers and safely-rounded interval arithmetic:

  • Dyadic: variable-precision floats with exact ring operations

  • MPBall: float ± error bound with field & elementary (interval-like) operations

There is a plan to add an Integer-only backend so that aern2-mp can be used without MPFR.
