Most computers these days use binary arithmetic. This means that they
can not store a number such as 10.11 exactly (or rather, they could
store it exactly, but they don't) so as your input is not stored exactly
you shouldn't expect exact results (from any computer arithmetic).
You can use the format-number function to round the result to 2dp.

don't do that, so this:

<xsl:variable name="SubTotals" select="/documents/value"/>
it's far more efficient and means that you would not need to use teh
node-set() extension to do the sum.
