[JEXL] Integer division

[Daniel Westheide]

Hello,

in the JEXL syntax reference - http://commons.apache.org/jexl/reference/syntax.html - it says that the div operator can be used to perform an integer division. In the example, "4 div 3" is supposed to give 1.

However, when I use the div operator in JEXL 1.0 or 1.1, its behaviour is identical to that of the division operator "/" - integer division simply seems not to be possible in JEXL. Is this a bug or is the documentation simply outdated?

Any help would be very much appreciated.

Best regards,

Daniel

A quick look at the JEXL parser code seems to suggest that div and /
are treated equivalently by the parser.

Unless anyone chimes in WRT that bit of documentation about integer
division (and/or the original intent for the operators), seems the
docs need to be changed.

It does seem the docs are out of whack...maybe a bug was introduced during
the 1.0 phase....

I should check the tests
