Data.Number.MPFR

functions ending with _ return a pair (value, rounding indicator). Rounding indicator indicates whether the result is rounded and in which directon as described in the MPFR manual.
the same functions without the _ return just the value.
functions with added "w" correspond to MPFR _ui functions
functions with added "i" correspond to MPFR _si functions

Equality testing

Equality works as follows:

NaN /= Nan,
Infinity = Infinity,
-Infinity = -Infinity
otherwise normal comparison

Ordering

Ordering works as follows:

compare NaN _ = GT
compare _ NaN = GT
infinity < _ = False
-infinity > _ = False
NaN [<,>,>=,<=] _ = False

This mimics the behaviour of built in haskell Float and Double.

Num instance

Operations defined in Num will be computed so that no precision is lost.
