Objective c division of two ints

Question

I\'m trying to produce a a float by dividing two ints in my program. Here is what I\'d expect:

1 / 120 = 0.00833

Here is the code I\'m using:

Answer 1

float a = 1/120;
float b = 1.0/120;
float c = 1.0/120.0;
float d = 1.0f/120.0f;

NSLog(@"Value of A:%f B:%f C:%f D:%f",a,b,c,d);

Output: Value of A:0.000000 B:0.008333 C:0.008333 D:0.008333

For float variable a : int / int yields integer which you are assigning to float and printing it so 0.0000000

For float variable b: float / int yields float, assigning to float and printing it 0.008333

For float variable c: float / float yields float, so 0.008333

Last one is more precise float. Previous ones are of type double: all floating point values are stored as double data types unless the value is followed by an 'f' to specifically specify a float rather than as a double.
