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

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

Parameters

x	-	floating point value
y	-	floating point value

Return value

true if x <= y, false otherwise

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<=.
