I'm making an equivalent of "sgn" function of BASIC language,

solve it?
Use isFloating!T and isIntegral!T traits.
The standard library **sng** function is a good example:

Of-course D has a built in "sgn" function, but I like to do it
with my hands to be sure of code, I'm some doubtful and don't
trust alien works.
