Objective c - Issue with float division

Question

I am trying to divide integer value by float, however getting wrong value. Please consider below example,

int a = 2;
float b = 10.0;
float result = a/b;

We are getting result as 0.200000003 instead of 0.2. I want use resulted value for other calculation. Please let me know how to solve this issue.

Use as for this

NSString *timeString = [NSString stringWithFormat:@"%.1f", result];
