What do you mean by "properly?" How, exactly, do you want the numbers rounded? What
about negative numbers?
There is a round() function that offers various options. I do not know how it handles
negative numbers, though.
For money numbers I found this to be a reasonable method:
sign = (0.0 <= N) ? 1 : -1;
tmp = abs(N);
tmp = round((tmp + 0.005), 2);
N = tmp * sign;
