Defined in header <cmath>
bool islessgreater( float x, float y );	(1)	(since C++11) (constexpr since C++23)
bool islessgreater( double x, double y );	(2)	(since C++11) (constexpr since C++23)
bool islessgreater( long double x, long double y );	(3)	(since C++11) (constexpr since C++23)
bool islessgreater( Arithmetic x, Arithmetic y );	(4)	(since C++11) (constexpr since C++23)

1-3) Determines if the floating point number x is less than or greater than the floating-point number y, without setting floating-point exceptions.

4) A set of overloads or a function template for all combinations of arguments of arithmetic type not covered by (1-3). If any argument has integral type, it is cast to double.

Parameters

x	-	floating point value
y	-	floating point value

Return value

true if x < y || x > y, false otherwise

Notes

The built-in operator< and operator> for floating-point numbers may raise FE_INVALID if one or both of the arguments is NaN. This function is a "quiet" version of the expression x < y || x > y.
