Separating digits from a float

I need a simple function that has 3 variables: l (left), m (middle), and r (right) So

int l,m,r

And when I put in the number 27.2 l should become 2 m should become 7 r should become 2 I can think of dividing the left 2 by deviding by 10 and then cast to int but the other 2 numbers?

Solution

  • Let your number be stored in x. 

    float x = 36.2;
x = x*10;
int r = (int)x%10;
x = x/10;
int m = (int)x%10;
x = x/10;
int l = (int)x%10;
printf("%d, %d, %d",l, m, r);
