Exponentiation

These instructions evaluate scalar powers and the natural exponential function.

Opcode	Arguments	Operands (stack)	Description
pow	type	base, exponent	Replaces the operands with an integer power; type must be sht, int, lng, or oct, and the top value is the exponent.
powi	type	base, exponent	Replaces the operands with a floating-point base raised to an integer exponent; type must be hlf, flt, or dbl, and the top value is the exponent.
powf	type	base, exponent	Replaces the operands with a floating-point power; type must be hlf, flt, or dbl, and the top value is the exponent.
exp	type	value	Replaces one operand with e raised to value; type must be hlf, flt, or dbl.
