i had to make a code for a GPA converter. every thing works fine when I put in a number like 83. But when I input a number with a decimal like 83.5 it prints out the else message for me. What am I missing?

Thats because 83.5 is not covered in your conditions. You have an option for >=84 and an option for <=83 but nothing between 83 and 84. Thus, when 83.5 is entered, it is neither >= 84 nor is it <= 83.

So you need to fix your conditions so every decimal is covered.
