| bool isless( float x, float y ); |
(1) | (since C++11) |
| bool isless( double x, double y ); |
(2) | (since C++11) |
| bool isless( long double x, long double y ); |

| bool isless( Arithmetic x, Arithmetic y ); |
(4) | (since C++11) |
1-3) Determines if the floating point number
x is less 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, 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<.
