.toFixed strangeness

Classic Servoy

I have a method that works out invoice totals from a given number:

var itemTotal = dataset.getValue(1,1);
if (itemTotal == null) itemTotal = 0;
var netTotal = itemTotal.toFixed(2);
var vat = netTotal * 0.175;
var vatTotal = vat.toFixed(2);
var inv = netTotal * 1.175;
var invTotal = inv.toFixed(2);
globals.g_invoiceQtyTotal = itemTotal;
globals.g_invoiceNet = netTotal;
globals.g_invoiceVat = vatTotal;
globals.g_invoiceTotal = invTotal;

My problem is that when the itemTotal equals 1903, the inTotal (ie 1903 plus 17.5 percent) comes out as 2236.023 even though it is supposed to be fixed to 2 decimal places. If i change it to toFixed(1) it comes out as 2236.0.

Anyone have any insight into why this is happening?

Searching for toFixed() gave me the two below posts on top. They both deal with your question:

Hope this helps

Thanks Marcel.

In the end I solved this one with the following revision:

var itemTotal = dataset.getValue(1,1);
if (itemTotal == null) itemTotal = 0;
var netTotal = itemTotal.toFixed(2);
var vat = netTotal * 0.175;
var vatTotal = vat.toFixed(2);
var inv = parseFloat(netTotal) + parseFloat(vatTotal);
var invTotal = inv.toFixed(2);
globals.g_invoiceQtyTotal = itemTotal;
globals.g_invoiceNet = netTotal;
globals.g_invoiceVat = vatTotal;
globals.g_invoiceTotal = invTotal;
