I have some features requests, some of which are small. Is there a way 
that these should be raised?

For example, this trivial feature could go in phobos2.std.math and tango:

float degToRad(float deg)
{
	return deg * PI / 180;
}

float radToDeg(float rad)
{
	return (180 * rad) / PI;
}

Or maybe ...

enum
{
   fPI_180 = PI / 180.0L;
   f180_PI = 180.0L / PI;
}

T degToRad(T)(T deg)
{
	return cast(T)(cast(real)deg * fPI_180);
}
 
T radToDeg(T)(T rad)
{
	return cast(T)(cast(real)rad * f180_PI);
}

that be different from just implementing in terms of real anyway. reals can be implictly converted down to a floats anyway, can they not? Seems like I should post this to digitalmars.D
