What is happening is that doing the arithmetic with the binary 
representations of 9.88 and 100 create a result in binary that when 
precisely converted to decimal give you the result you see.

As Martin suggests, if you are using XSLT 2 then you can use decimal 
representations of your values and do arithmetic with those.

I hope this helps understand the issue.
