Arithmetic is provided to act on integer (BigInteger and Long) and floating point�(BigDecimal and Double) values. There are 5 operators:
- Addition: +
- Substraction: -
- Multiplication: *

- Remainder (modulo): % and mod
The last two operators are available in both syntaxes to be consistent with XPath and�ECMAScript.
