With a small counting I've seen that in my code I have often to cast the result
of the functions floor/round/ceil to integral values, like:

cast(ubyte)round(x)
cast(int)floor(y)

But I prefer to avoid casts in my code. So I suggest to modify them (or to add
new small functions) in Phobos that accept a template argument to specify the
result integer type:

round!ubyte(x)
floor!int(y)
