Given x : float; i : integer; then the line if (i > x) then ... won't work, since ">" isn't defined between integers and floats. This is perhaps what is meant: if float(i) > x then ... However, this does not really help the hard-core numerical programmer, who most likely wants X rounded but left in FLOATING representation - since otherwise he can use only a very restricted subrange of float. What we really need is the set function FLOOR (X : FLOAT) return FLOAT; CEIL ROUND TRUNC and let's make them generic in the domain type.
