If numerator and denominator are both integers, then division will be integer. Use
float answer = 4/(float)3
Question
I tried to calculate 4/3 and store it into a float.
float answer = 4/3;
This only returns 1. Isn't objective-c able to calculate these kinds of fractions or do I have to do it any other way?
Solution
If numerator and denominator are both integers, then division will be integer. Use
float answer = 4/(float)3
OTHER TIPS
4
and 3
are integers. So that division is an integer division, which evaluates to 1
.
If you want a floating-point division, use (at least one) float literal.
float answer = 4f/3;
Your assignment contains an integer divide, which returns zero if the number you are dividing by is greater. You probably meant to do:
float p1 = (4.0f / 3.0f);
or
float p1 = ((float)4 / 3);
