I got my calculator gui working and it can work with decimals but i need i to work with fractions only or both. I made a new button for the fractions which is x\y because \ is allready taken by divide. If anyone could help me make this calculator do fractions that would be great. thanks

yah know, fractions and division go hand in hand, which is why they use the / sign

3/4 = 0.75

knowing this you could simply have the user enter fractions as "3/5" and have the program take it explicitly, and peform the division.

but, probably already knowing this, your best bet would be to store the numerator and the denominator as two seperate variables, and use the '\' as the dilimeter for input.

There's a code snippet using a Class to use Fractions.
Try and see if that helps.
HERE

Besides, if you want to do something in particular with the fractions, let us know. That way it's easier to help.

well if the numerator can be divided into the denominator with 0 remainder, it can be simplified

for instance if you were presented with the input "2/4"



CODE
(2 % 4) % 4


this would equate to 0, meaning that they can be divided be each other, or in other words they can be simplified.

CODE
(numerator % denominator) % denominator


knowing that the fraction needs to be simplified you could simplifgy it the same way with %(modulus)

Relax...read the code snippet carefully.
It simplifies fractions...always...

1/4 will always be zero. If you're attempting to multiply numerator/denominator by another number, then you ought to multiply the numerator on its own, then use the denominator to work out your new number as a fraction
