Click on the green flag. Then, enter a decimal number. The program will convert it into a fraction. The one problem is that sometimes, the program is unable to calculate for large decimals, and sometimes, it can lag. If the fraction doesn't appear after a while, try hitting space. If it shows infinity/infinity, then it means it either wasn't finished calculating, or there is a glitch (most probably it wasn't finished calculating)
Once I make a better GCF algorithm (if it is possible), then this will become quicker.
