***Note from Migration:***
Original Title was: @round() expression evaluator function should have an argument to round to a specific number of decimals
Currently the @round function takes one argument, the value to round, and rounds it to the nearest integer. It would be nice is there was an optional second argument to specify the number of decimal places to round to (like AttributeRounder transformer), if the second argument is not supplied, then it should round to the nearest integer.
