But they all have a largest and smallest possible value, as I have
already indicated.

Not all FP representations have infinity, and even if
they do, they might only have one infinity.

I've previously mentioned that I would like to see an 'instance
Bounded Double' etc., as part of the standard, which would use 1/0 for
maxBound, or the largest possible value (there must be one!) for
platforms where that is not possible. I don't see a problem with
looking at Double values as if the
Hi Jacques,
Thanks also to you for a most interesting reply.
This same discussion has taken place on the
discussion list of every modern general-purpose
programming language.
The same points are always raised and argued, and
the conclusion is always the same: floating point
exceptions should rai

Oops. Thanks! Thanks also to Lennart
The RealFloat class has a number of methods for testing
various properties of a FP number:
isNaN :: a -> Bool
isInfinite :: a -> Bool
isDenormalized :: a -> Bool
isNegativeZero :: a -> Bool
isIEEE :: a -> Bool
If you really want to create an Infinity, I suggest 1/0,
but not all FP forma
The IEEE 754 standard says (fairly clearly) that +1.0 / +0.0 is one of
the most 'stable' definitions of Infinity (in Float at least).
Throwing an exception is also regarded as a possibility in IEEE 754, but
it is expected that that is not the default, as experience shows that
that is a sub-
