Defined in header <cmath>
float       fmax( float x, float y );
(1) (since C++11)
double      fmax( double x, double y );
(2) (since C++11)
long double fmax( long double x, long double y );
(3) (since C++11)
Promoted    fmax( Arithmetic x, Arithmetic y );
(4) (since C++11)

Returns the larger of two floating point arguments.

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 values

Return value

The larger of two floating point values.
