Puppet won't be able to do the initial arithmetic within the braces because $::processorcount is a string. So you might end up with something like "multiply_floor($::processorcount, 0.8)" or "floor(str2int($::processorcount) * 0.8)". Alternatively the cheap and hacky approach: $foo = inline_template("<%= (processorcount.to_i * 0.8).floor -%>") -- You received this message because you are subscribed to the Google Groups "Puppet Users" group.
