There may be something in std.math which makes it cleaner, but
I would have
thought that the to test whether a floating point value is an
integral value,
you'd just cast it to an integral type and then compare that
against the
original. e.g.
auto isIntegral = cast(int)my_float == my_float;

Isn't type conversion:
auto isIntegral = to!int(my_float) == my_float;
more recommended/idiomatic D way to deal with built-in types?
