Defined in header <cmath>
bool isunordered( float x, float y );		(desde C++11)
bool isunordered( double x, double y );		(desde C++11)
bool isunordered( long double x, long double y );		(desde C++11)

Determina si los números de punto flotante y x y están ordenados, es decir, uno o ambos están NaN y por lo tanto no pueden compararse entre sí .

Original:

Determines if the floating point numbers x and y are unordered, that is, one or both are NaN and thus cannot be meaningfully compared with each other.
