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

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

Contents

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<.
