Math.Round error

[GKonheiser]

Hi,

I am trying to round to the nearest whole number 90 % of the count of a list but get the error;

"The call is ambiguous between the following methods or properties: 'System.Math.Round(double, int)' and 'System.Math.Round(decimal, int)'"

and this

Cannot implicitly convert type 'double' to 'int'. An explicit conversion exists (are you missing a cast?)

This is my code;

y = Math.Round(myList.Count * 90/100,0);

GKonheiser,

Thank you for your note.

You need to specifically cast the double or decimal type in this instance.

(double)(myList.Count * 90/100)

Use the above in your Math.Round() to get the value of myList.Count * 90/100 specifically as a double

im obviously not getting it, i tried,

Math.Round(decimal)(list.count * 90/100)

and a few other variations but its not liking it, what am i doing wrong, I want to round to the nearest whole number?

GKonheiser,

You still need the () for the Math.Round method, that has not and will not change.

Math.Round((double)(myList.Count * 90/100), 0);
