Expressions



For simplicity's sake only expressions with two operands are allowed.

Boolean expressions:


This operations are supported for boolean expressions:

Operator Example
and res = b1 and b2
or res = b1 or b2
> res = n1 > 5
< res = n1 < 5
== res = n1==n2 (comparison is also supported between boolean and string operands!)

this kind of expressions can be also used directly as "if's conditions" like this:

Numerical expressions:


This operations are supported for numerical expressions:

Operator Example
+ n1 = n1 + 1
- n2 = n1 - n3
* n3 = n1 * 7
/ n3 = n2 / n1

this kind of expression can be also used directly to determine the start value of a for loop's index like this:

Strings expressions:

Operator Example
+ res = "hello " + "world"

You can concatenate two strings in AVIL just by usign the "+" operator like this:
