best to do math in the SQL of the query itself (if you are running a query):
SELECT sum(hours) AS totalHours,
sum(hours * 65) AS totalCost
FROM hoursTable
WHERE bla = bla
CF is extremely slow compared to enterprise level databases such as SQL
Server 7 and Oracle. If you insist on using CF, however, do this:
<cfset totalHours = arraySum(getHours)>
<cfset cost = totalHours*65>
<CFOUTPUT>
<P>The sum of the numbers is #totalHours# hours. At $65/hr,
this equals #dollarformat(cost)#
</CFOUTPUT>
Just leave the the ArraySum function out of the CFOUTPUT tags and you won't
get the YES output

Subject: Populate array with query
Hi,
Can someone suggest a better way to sum a numeric column in a query? The
solution is probably painfully simple, but I've been struggling for an hour
or two on it (only have online docs available).
<CFOUTPUT>#ArrayDeleteAt(GetHours,1)#</CFOUTPUT>
<CFLOOP query="getMainList">
<CFOUTPUT>#ArrayAppend(GetHours, "#numberformat(hours)#")#</CFOUTPUT>
</CFLOOP>
Line 3 produces a string of "YES"s at the top of my output- one for every
record in the query.
The following gives me the result I need, but I can't get around the
display of the YES's that appears.
<cfset cost = ArraySum(GetHours)*65>
<CFOUTPUT>
<P>The sum of the numbers is #ArraySum(GetHours)# hours. At $65/hr,
this equals #dollarformat(cost)#
</CFOUTPUT>
TIA,
--John
