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)
}
