Numeric operators in Perl are as follows :
* Arithmetic operators : (+,-,*/).
* Comparison operators : to compare two numbers (>, <, ==, !=,<=,>=,<=>).
* Bitwise Operators : (&(and), |(or),^(ex-or),~(not),<<(shift left),>>(shift right)).
Arithmetic operators perform from left to right while Bitwise operators perform an operation from right to left.
