[Edu-sig] Exponentiation should float
Tue, 15 Feb 2000 16:38:13 -0500
The problem is that exponentiation goes, well, exponential. So it is real
easy for this operation to give a result too large even for long integers.
A more general statement would be that if there is overflow on integer
exponentiation, the operation should be repeated with a floating result.
