Hi

can someone help me out with this if possible, I dont know if its a bug or just bad coding on my part, but its driving me mad!!!

I building a math program to help kids.  
one of the test I’ve build comes up with a intermittent error

it works by pulling five numbers from an array between 0 and 99 and then divides it by 10  
then its mulitplied by either 10 or 100 (this is done by random)

the error that I am getting is that when certain number combinations come up the answer is wrong even if the user enters the correct answer

the numbers that seem to be a problem are  
4.4 \* 100  
4.1 \* 100  
1.1 \* 100  
4.6 \* 100  
4.9 \* 100  
8.8 \* 100  
there could be others but these are the one I’ve found so far

I am stumped with this, can anyone help??
