Enum member std.traits.isFloatingPoint
Detect whether T
is a built-in floating point type.
enum isFloatingPoint(T)
= __traits(isFloating, T) && is(T : real);
Example
static assert(
isFloatingPoint!float &&
isFloatingPoint!double &&
isFloatingPoint!real &&
isFloatingPoint!(const(real)) &&
isFloatingPoint!(immutable(real))
);
static assert(!isFloatingPoint!int);
// types which act as floating point values do not pass
struct S
{
float val;
alias val this;
}
static assert(!isFloatingPoint!S);
