Math funtions not in document

I am wondering how many math functions in CF8 not listed in documents?

I do use (x mod y) and works fine but mod is not listed in the document and not in math category.

Can somebody give me a complete list of math functions available in CF8?

thank you very much

<cfif (getOpp.recordcount mod pagerows) eq 0>
<cfset pageCount = int(getOpp.recordcount / pagerows)>
<cfelse>
<cfset pageCount = int(getOpp.recordcount / pagerows) + 1 >
</cfif>
