Module rgsl::power
[−]
[src]
The following functions are equivalent to the function gsl_pow_int (see 1Small integer powers1) with an error estimate.
Functions
pow_int |
This routine computes the power xn for integer n. The power is computed using the minimum number of multiplications. For example, x8 is computed as ((x2)2)2, requiring only 3 multiplications. For reasons of efficiency, these functions do not check for overflow or underflow conditions. |
pow_int_e |
This routine computes the power xn for integer n. The power is computed using the minimum number of multiplications. For example, x8 is computed as ((x2)2)2, requiring only 3 multiplications. For reasons of efficiency, these functions do not check for overflow or underflow conditions. |
