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 -DHUGS=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.
This installation was compiled with the normal Prelude version. This should be correct.
