Calculation

[CaesarII]

Hi I'm attempting to use XSL to caluclate the grand total for two invnoices, whilst the calculation provides a number, on the first invoice's grand total, the number is off by 0.05 and on the second invoice there is "000000000001" after the correct first two decimal places. This is the XSL code I'm using to make the calculation:<td style="text-align:center;"> <strong><xsl:value-of select="sum(//item_price)" /></strong> </td> CaesarII

The following code is a snipit of my xml code in case its useful <invoice> <item_id>11224432</item_id> <name>Toshiba Laptop</name> <photo> <img src="images/Laptop.jpg" /> </photo> <item_price>125.00</item_price> <price>125.00</price> </invoice>

I’ve figured out why the first calculation was wrong, I’d entered the information wrong. However the second calculation, the one with "000000000001" at the end of it, is still incorrect, I’ve also discovered that this calculation goes wrong at between 0.45 & 0.46 (with the total being 74.49000000000001)

i've come up with a soloution, it isen't the most elegent, but it woks. In the XML document i added a secondn item price to the affected calculation which was "-0.000000000001"
