Question

I thought this would be simple, but searching Google didn’t seem to help.

I’m basically trying to write a function which will return a ratio as a string (eg 4:3) when supplies with two integers (eg 800 and 600).

string GetRatio(Int A, Int B) {     // Code I'm looking for     return Ratio; } 

Answer 1

You can simplify fractions by dividing numerator and denominator by their GCD:

var gcd = GCD(A, B); return string.Format('{0}:{1}', A / gcd, B / gcd) 

And a very basic function for calculating the GCD, using the Euclidean algorithm:

static int GCD(int a, int b) {     return b == 0 ? Math.Abs(a) : GCD(b, a % b); }
