Comment(by tristes_tigres):

 Thoughts about the right (meaning, in the spirit of IEEE754) way to fix
 this:

 Operations truncate, round, ceiling and floor on a floating-point type
 should return floating-point type, not integral. The operation of rounding
 need not and should not be combined with type conversion.
