The negative number should come out with a - sign already. So once you've used .ToString, if the first char isn't a '-' then put a '+' at the start:

double x = 500.12;
double y = -500.12;

string sX;
string sY;

sX = x.ToString();

if(!sX.StartsWith("-"))
sX = "+" + sX;

sY = y.ToString();

if(!sY.StartsWith("-"))
sY = "+" + sY;

Console.WriteLine(sX + "\n" + sY);

The output should be: +500.12 -500.12

My current favourite word is: PIE! Good ol' pie, it's been a while.

Thanks for the opportunity to look into this.:-D

System.Console.WriteLine ( ( 500.12).ToString("+#.##;-#.##" ) ) ;
System.Console.WriteLine ( (-500.12).ToString("+#.##;-#.##" ) ) ;

Works like a charm. Thanks.
