Hugs.RealFloat
Description
Hugs (September 2006) has buggy definitions for isNaN
and isInfinite on Float and Double. If this module is
run through CPP with the macro __HUGS__ set to a value no
larger than 200609, then correct definitions are used. Otherwise
the Prelude definitions are used (which should be correct for
other compilers). For example, run Hugs with
hugs -F'cpp -P -D__HUGS__=200609' Hugs/RealFloat.hs
N.B. The corrected definitions have only been tested to work for
Float and Double. These definitions should probably not be
used for other RealFloat types.
