| float fdim( float x, float y ); |
(1) | (since C++11) |
| double fdim( double x, double y ); |
(2) | (since C++11) |
| long double fdim( long double x, long double y ); |
(3) | (since C++11) |
| Promoted fdim( Arithmetic x, Arithmetic y ); |
(4) | (since C++11) |
Returns the positive difference between x and y. This could be implemented as fmax (x - y, 0), so if x ≤ y, the result is always equals to 0, otherwise it is x - y.
4) If any argument has integral type, it is cast to double. If any other argument is long double, then the return type is long double, otherwise it is double.
Parameters
| x, y | - | floating point value |
Return value
The positive difference value.
