# Power Function¶

gsl_sf_pow_int(x, n)

This routine computes the power $$x^n$$ for integer $$n$$. The power is computed using the minimum number of multiplications. For example, $$x^8$$ is computed as $$((x^2)^2)^2$$, requiring only 3 multiplications. For reasons of efficiency, these functions do not check for overflow or underflow conditions.
