Whenever I use fractional numbers in my programs, I always use rounding before printing them. For example: 
$i= int($i*100+.5)/100;

This makes sure you get exactly two numbers after the point. If I don't want to round the number I still add a small fractional number instead of 0.5, so that I don't get 5.99 if it really should be 6.00
