# std::islessgreater

From cppreference.com
< cpp‎ | numeric‎ | math

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

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.

### [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.
