RE: [xsl] Decimal precision

["Michael Kay" <mike@xxxxxxxxxxxx>]

With XSLT 2.0 

(a) a numeric literal such as 1.0 is interpreted as a decimal value

(b) you can force numbers to be treated as decimal values by casting

     e.g. xs:decimal($x)

(c) the result of an operation on two decimals, e.g. $x div $y, is itself
    a decimal (though with division, the precision is
implementation-defined)

(d) if you have a schema, and the schema defines the type of an element
    or attribute as decimal, then it's automatically treated as decimal
    without needing an explicit cast (like in (b)).

So summing a set of money amounts should give you the right answer without
any rounding errors.
