-"""Utilities for handling IEEE 754 floating point special values
-
-This class implements constants and functions for working with IEEE754
-double-precision special values.  It provides constants for NaN (Not a
-Number), NegInf (Negative Infinity), PosInf (Positive Infinity), and
-Inf (also Positive Infinity), as well as functions to test for these
-values.
-
-The code is implemented in pure python by taking advantage of the
-'struct' standard module.  Some efficiency could be gained by
-translating the core routines into C.
-
-See <http://babbage.cs.qc.edu/courses/cs341/IEEE-754references.html>
-for a description of the IEEE 754 floating point standard.
