Saseflower, The fraction function is not working properly at the moment.   :(

Hopefully it will be fixed soon ://

Yes, I was looking for it so hard! But I couldn't find it!!!!!!!!! PLEASEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEE!!!!!!!!!!!!!!!

There already are fractions available in the calculator. When you get to the calculator, click the button on the far right in the area where if you clicked numbers, they would appear. Then, it should say Scientific, Programmer, and then input helpers. Under input helpers, click Fractions. There you go!

It's fixed now, YAY

EDIT:the programmer mode has more mathematics stuff than scientific.

You can add fractions in the scientific part of the calculator, but the specific section of the calculator devoted to fractions still doesn't work (29th Oct. 2015).
