Defined in header <cmath>
bool islessequal( float x, float y );
(1) (since C++11)
bool islessequal( double x, double y );
(2) (since C++11)
bool islessequal( long double x, long double y );
(3) (since C++11)
bool islessequal( Arithmetic x, Arithmetic y );
(4) (since C++11)
1-3) Determines if the floating point number x is less than or equal to 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, false otherwise

[edit] Notes

The built-in 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 operator<=.
