Function std.math.operations.fmax

Returns the larger of x and y.

F fmax(F) (
  const F x,
  const F y
) pure nothrow @nogc @safe
if (__traits(isFloating, F));

If one of the arguments is a NaN, the other is returned.

See Also

max is faster because it does not perform the isNaN test.

Example

import std.meta : AliasSeq;
static foreach (F; AliasSeq!(float, double, real))
{
    writeln(fmax(F(0.0), F(2.0))); // 2.0
    writeln(fmax(F(-2.0), 0.0)); // F(0.0)
    writeln(fmax(F.infinity, F(2.0))); // F.infinity
    writeln(fmax(F.nan, F(2.0))); // F(2.0)
    writeln(fmax(F(2.0), F.nan)); // F(2.0)
}
