[%CFEngine_function_prototype(list)%]
Description: Return the sum of the reals in list
.
[This function can accept many types of data parameters.][Functions#collecting functions]
This function might be used for simple ring computation. Of course, you could
easily combine sum
with readstringarray
or readreallist
etc., to collect
summary information from a source external to CFEngine.
[%CFEngine_function_attributes(list)%]
Example:
[%CFEngine_include_snippet(sum.cf, #+begin_src cfengine3, .*end_src)%]
Output:
[%CFEngine_include_snippet(sum.cf, #+begin_src\s+example_output\s, .end_src)%]
Because $(six)
and $(zero)
are both real numbers, the report that is
generated will be:
six is 6.000000, zero is 0.000000
Notes:
History: Was introduced in version 3.1.0b1,Nova 2.0.0b1 (2010). The [collecting function][Functions#collecting functions] behavior was added in 3.9.
