Prototype: product(list)

Return type: real

Description: Returns the product of the reals in list.

This function might be used for simple ring computation. Of course, you could easily combine product with readstringarray or readreallist etc., to collect summary information from a source external to CFEngine.

Arguments:

  • list: string, in the range: [a-zA-Z0-9_$(){}\[\].:]+

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
