x raised to the power of n. If n is negative the result is 1 / pow(x, -n), which is calculated as integer division with remainder. This may result in a division by zero error.
If both x and n are 0, the result is 1.
If x is 0 and n is negative, the result is the same as the result of a division by zero.
