It is pretty useless. If you are doing exact math, fractional exponents
don't fit. If you are using integer exponents, you can store usable
exponents in an int (arguably an an int2).
People may be interested in NUMERIC^NUMERIC MOD N, but if so they aren't
going to do the exponentation first and then the mod operation.
