The Inf and NaN handling of the current library is alpha quality at
best, and far away from being compatible with current standards.  I
wouldn't trust it more than comparing the result of an operation
against NaN, in order to escape then.

Also, since there are no options to signal something, it's not even
possible to go the `historic' route of trapping arithmetic errors.
