enum isFloatingPoint(T) = __traits(isFloating, T) && is(T : real);

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