Question

As title states, if I have a float, I need to get the fraction part as an integer, how do I do it?

I was thinking:

1. get index(position) of decimal point
2. then I can know how many digits after decimal point
3. get those digits as substring
4. convert it to an integer

is there any better/smarter way?

update:

I forgot to mention, the float has format like: X.YZ so there are at most two digits after decimal point.

Answer 1

 float temp=12.123;
NSString *str=[NSString stringWithFormat:@"%f",temp];
NSArray *arr=[str componentsSeparatedByString:@"."];
int tempInt=[[arr lastObject] intValue];
