format as a positive number regardless if pos or neg 1

[tester321]

Hi i have a number that sometime might be negative, but that screws up the senerio, so for a plave where there might be a negative number i would like to covert it to a positive, this is what i have which isn't working


Response.Write( (int)Math(Abs(Convert.ToInt32(listpc[index].val))) );

so if i the array value is -5 i need it to be 5, and if its 5 then stays positive.

Thanks

int[] numbers = new int[] { -2, -1, 0, 1, 2 };
foreach(int number in numbers)
{
   Console.WriteLine(Math.Abs(number));
}

results
[tt]
2
1
0
1
2
[/tt]

-1 is not replaced by 1 Math.Abs() returns a new object with a value of 1, so the array still contains [tt]-2, -1, 0, 1, 2[/tt]

in your case, you can remove the (int) cast. the value of [tt]listpc[index].val[/tt] is still negative, but the result of [tt]Math.Abs(listpc[index].val)[/tt] is a new postive integer
