in practice numbers in xslt either come from text strings in the source
and have a fixed number of decimal places (like 2:-) in which case of
course equality testing works fine, or you have done some arithmetic and
you want to compare as integers in which case you can use floor() and
friends before making the comparision, these are defined to return
integer valued floating point numbers. Again since this is typically
something like the number of rows of a table div 3, you don't get into
trouble with loss of precision on large integers, as the numbers are not
that large (as a rule).

It is not leading edge numerical analysis but it works well enough in
the scenarios that XSLT was designed for.
