Hi Guys,

I am new to dotnet and have this custom function to show a £value saving
based on the ProdPrice and ProdWPrice which works fine, but I am looking for
the value to be shown as a percentage % rather that a £value for another
function.


public static string saving(object ProdPrice, object ProdWPrice)
{

if (ProdPrice == null || ProdWPrice == null)
{
return "";
}
else
{
Double ProdPriceNew = Convert.ToDouble(ProdPrice);
Double ProdWPriceNew = Convert.ToDouble(ProdWPrice);
Double Saving = Math.Round (Convert.ToDouble(ProdWPriceNew -
ProdPriceNew),2);

if (Convert.ToInt32(Saving) <=0)
{
return "";
}
else
{
return "Save " + Saving.ToString("c");
}
}

Thanks

}

You want Saving as a percentage of what? Regardless, it's a matter of doing
the math. Do whatever division is needed to get the decimalfraction (e.g.
0.1325). Multiply the result by 100 (0.1325 becomes 13.25). Then add a "%"
to the output string.

You can also use the "P" format specifier with ToString() to automate the
multiplication and addition of the "%".
