Ah, but it is not as accurate!
If the original poster knows he needs fractions, he won't be happy with float.
Just as one should NEVER use floating point to represent money, one should NEVER use it
for representing fractions that need to be precise. For example, (1/3 as a float) * 3 will
come out to 0.99999999.
