== Description

Special value handling: * If `from` equals `to`, `to` is returned. * If either argument is quiet NaN, quiet NaN is returned. * If either argument is signaling NaN, quiet NaN is returned and the value of the macro `EDOM` is stored into `errno`. * If `from` is finite, but the expected result is infinity, infinity is returned and the value of the macro `ERANGE` is stored into `errno`. * If `from` does not equal `to` and the result is subnormal or zero, the value of the macro `ERANGE` is stored into `errno`.
