This function creates a new constrained expression equal to the base x raised to the power p, that is, xp. If p is a floating-point value, then x is constrained to be greater than or equal to 0 (zero). The argument p must be different from 0 (zero). The effects of this function are reversible.

If the arguments are simply floating-point numbers (that is, they are not constrained expressions), it merely returns an instance of IlcFloat equal to the base raised to the power. The base should be greater than 0 (zero).

The distinction between the two versions (whether the exponent is integer or floating-point) of this function is not always handled correctly by certain C++ compilers. To cope with their vagaries, if you want to use the integer exponent version, add L (for long) after the exponent, like this:

 IlcPower(x, 19L);
