Formatting a users answer

I am writing a simple learning program that does basic math. Everything is working as needed except for when it comes to division. I need to know if there is a way to format the users input to two decimal places and that when the program checks the users answer against the division, it gives it a yay or nay. Right now, it wants the answer out to 12 decimal places.

So for 5/3















I would like it to accept the answer 1.67

not 1.666666666667

Is there a way to do this?

If you need more information, please let me know, I can upload a code snipet if needed as well.

Thanks in advance!
