smartOp.pow

Raise base to the exp power.

Errors that may be signalled if neither input is floating-point:

IntFlag.posOver or IntFlag.negOver if the absolute value of the result is too large to represent with the return type.
IntFlag.div0 if base == 0 and exp < 0.

5 assert(smartOp.pow(2, -1) == 0);
6 
7 smartOp.pow(-3, 27);
8 assert(IntFlags.local.clear() == IntFlag.negOver);
9 smartOp.pow(0, -5);
10 assert(IntFlags.local.clear() == IntFlag.div0);
