Enum member `std.traits.isFloatingPoint`

Detect whether T is a built-in floating point type.


						
				enum isFloatingPoint(T)
				 = __traits(isFloating, T) && !(is(Unqual!T == cfloat) || is(Unqual!T == cdouble) || is(Unqual!T == creal) || is(Unqual!T == ifloat) || is(Unqual!T == idouble) || is(Unqual!T == ireal));

Example

static assert(
    isFloatingPoint!float &&
    isFloatingPoint!double &&
    isFloatingPoint!real &&
    isFloatingPoint!(const(real)) &&
    isFloatingPoint!(immutable(real))
);

static assert(!isFloatingPoint!int);

// complex and imaginary numbers do not pass
static assert(
    !isFloatingPoint!cfloat &&
    !isFloatingPoint!ifloat
);

// types which act as floating point values do not pass
struct S
{
    float val;
    alias val this;
}

static assert(!isFloatingPoint!S);
