easily combine product

or readreallist
etc., to
collect summary information from a source external to CFEngine.
This function can accept many types of data parameters.
Arguments:

:string
, in the range:.*
Example:
body common control
{
bundlesequence => { "test" };
}
bundle agent test
{
vars:
"series" rlist => { "1.1", "2.2", "3.3", "5.5", "7.7" };
"prod" real => product("series");
"sum" real => sum("series");
reports:
"Product result: $(prod) > $(sum)";
}
Output:
R: Product result: 338.207100 > 19.800000
