!! Major Improvements

Added several new [[Mathematics Operators]] for working with numbers: [[negate|negate Operator]], [[abs|abs Operator]], [[ceil|ceil Operator]], [[floor|floor Operator]], [[round|round Operator]], [[trunc|trunc Operator]], [[untrunc|untrunc Operator]], [[sign|sign Operator]], [[add|add Operator]], [[subtract|subtract Operator]], [[multiply|multiply Operator]], [[divide|divide Operator]], [[remainder|remainder Operator]], [[max|max Operator]], [[min|min Operator]], [[fixed|fixed Operator]], [[precision|precision Operator]], [[exponential|exponential Operator]], [[sum|sum Operator]], [[product|product Operator]], [[maxall|maxall Operator]] and [[minall|minall Operator]].
