These functions previously returned partial NaN values (
NaN + 0i) when input was NaN.This patch explicitly checks
std::isnan(x)and returnsComplex(x, x), ensuring bothreal and imaginary parts propagate NaN consistently. Verified with test cases in Octave REPL:
rc_sqrt(NaN) -> NaN + NaNi
rc_log(NaN) -> NaN + NaNi
