From cppreference.com
< cpp‎ | numeric‎ | math

Defined in header `<cmath>` |  |
bool islessgreater( float x, float y ); |  | (since C++11)
bool islessgreater( double x, double y ); |  | (since C++11)
bool islessgreater( long double x, long double y ); |  | (since C++11)

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

### [edit] Parameters

x | - | floating point value
y | - | floating point value

### [edit] Return value

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

### [edit] 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.
