Be aware that there is no strict rule on the integer size in NASL2.
The interpretor implements them with the native ``int'' C type,
which is 32 bit long on most systems, and maybe 64 bit long on a few
one^{7}. There is no overflow or underflow protection.

`+`is the addition operator.`-`is the subtraction operator.`*`is the multiplication operator.`/`is the integer division operator. Please note that:- NASL2 does not support floating point operations.
- Division by zero will return 0 instead of crashing the interpretor. How nice of us!

`%`is the modulo. Once again, if the 2 operand is null, the interpretor will return 0 instead of crashing on SIGFPE.`**`is the exponentiation or power function^{8}.
