++

changes its operand to its successor, is itself no int expression

--

changes its operand to its predecessor, is itself no int expression

+

addition

-

negation or subtraction

*

multiplication

div

integer division (omitting the remainder), rounding toward 0

%, mod

integer modulo (the remainder of the division

^, **

exponentiation (exponent must be non-negative)

<, >, <=, >=, ==, <>

comparators

Note: An assignment j=i++; or j=i--; is not allowed, in particular it does not change the value of j, see Limitations.

Example:

int i=1; int j; i++; i; i--; i; ==> 2 ==> 1 // ++ and -- do not return a value as in C, cannot assign j = i++; ==> // ** right side is not a datum, assignment ignored ==> // ** in line >> j = i++;<< // the value of j is unchanged j; i; ==> 0 ==> 2 i+2, 2-i, 5^2; ==> 4 0 25 5 div 2, 8%3; ==> 2 2 -5 div 2, -5 mod 2, -5 % 2; ==> -2 -1 -1 1<2, 2<=2; ==> 1 1
