Math.Ceiling, how to cast the value, proper synthax?

[Greenwood]

Hi Im trying to Math.Ceiling with the following code, where fr is a array of doubles and max is an int, it give me the following error "Error The call is ambiguous between the following methods or properties: 'System.Math.Ceiling(decimal)' and 'System.Math.Ceiling(double)'"

for (int i = 0; i < fr.Length; i++)
            {
                if (fr[i] < max)
                {
                    max = (int)Math.Ceiling(i);
                }
            }
 

Please advise Thanks

Maybe you made a typo?

            for (int i = 0; i < fr.Length; i++)
            {
                if (fr[i] < max)
                {
                    max = (int)Math.Ceiling(fr[i]);
                }
            }

If it's not a typo, than you can cast i to double and it should work (max = (int)Math.Ceiling((double)i);)
