Just to comment on zariok's comment (which is right below mine), his problem is likely due to
the fact that decimal numbers (such as 0.5500) cannot be exactly represented in binary (and hence
computers can't precisely determine that 0.5500 * 100 = 55).
This feature is great when you know that your result is going to be nowhere near an integer (for
example, finding ceil(1/3) will confidently give a 1). However in situations like his, this is
probably not the better function to use.
