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

As answered earlier, subtracting is the way to go. Just remember to convert the one tenths of feet to inches by multiplying with 12:

float totalHeight = 5.122222;
int myFeet = (int) totalHeight;
float myInches = (totalHeight - myFeet) * 12;
