iOS objective-C: using modulo on a float to get “inches” from Feet

Question

I am trying to make a simple objective-C height converter. The input is a (float) variable of feet, and I want to convert to (int) feet and (float) inches:

f         


        

Answer 1

Even modulo works for float, use :

fmod()

You can use this way too...

float totalHeight = 5.122222;
float myFeet = (int) totalHeight; //returns 5 feet
float myInches = fmodf(totalHeight, myFeet);
NSLog(@"%f",myInches);
