Sebb commented on JEXL-50:
--------------------------

Just found out: the JSP 2.0 documentation states that "/" and "div" are equivalent in the expression language so perhaps it is the documentation that is wrong.
The division will return a BigDecimal if either input is BigDecimal or BigInteger, but the division is rounded up.

Likewise, Velocity returns an integer if the operands are integers - but I'm not sure what rounding is applied.

It would be useful to have an IntegerDivide operator, but perhaps it needs a new token.

> The "div" operator behaves the same as "/" - however it should do integer division according to the web-site:
