As part of a calculator app, I am trying to implement uses with sigma notation. However, the result it prints out is always a decimal, and the rest isn't important. I simply want to change the decimal to a fraction.
I already have the reduce function, the problem I'm having is getting from a decimal like this: '0.96875' to it's fractional value, '31/32'
Thanks!
PS: I've looked into just about everything, and for the life of me, I can't figure this out. All I need at this point is how to take the decimal out of it, and I can then reduce it.
Here is my reduce method:
-(void)reduce {
int u = numerator;
int v = denominator;
int temp;
while (v != 0) {
temp = u % v;
u = v;
v = temp;
}
numerator /= u;
denominator /= u;
}
Found this out myself. What I did was multiply the numerator and denominator by 1000000 (recalling that the decimal looked like .96875/1) so that it looked like
96875/100000
.Then, I used this reduce method to bring it into lowest terms:
And finally,I used a print method to get it into fraction form:
And got my desired output:
