Parameters. Return value. If no errors occur, square root of arg (√arg), is returned. If a domain error occurs, an implementation-defined value is returned (NaN where supported). If a range error occurs due to underflow, the correct result (after rounding) is returned. Error handling. Errors are reported as specified in math_errhandling.
