== Description

Special value handling: * If `base` is finite and negative and `exp` is finite and non‐integer, quiet NaN is returned and the value of the macro `EDOM` is stored into `errno`. * If the mathematical result of this function is infinity or undefined or a range error due to overflow occurs, infinity is returned and the value of the macro `ERANGE` is stored into `errno`. * If a range error occurs due to underflow, the correct result (after rounding) is returned and the value of the macro `ERANGE` is stored into `errno`. * If either argument is signaling NaN, quiet NaN is returned and the value of the macro `EDOM` is stored into `errno`.
