3. Mathematical & Logical Operators

Because Aergia uses prefix notation, binary operations consume the next two valid parsed sub-expressions. Unary operations consume exactly one.

Binary Syntax: [operator] [operand_1] [operand_2] Unary Syntax: [operator] [operand]

Binary Operators

+ Addition / String Concatenation (Auto-formats)
- Subtraction
* Multiplication
/ Division
^ Power
% Modulo

Bitwise Operators

& Bitwise AND
| Bitwise OR
$ Bitwise XOR
~ Bitwise NOT (Unary)

Comparison Operators

These evaluate to 1 if the condition is true, or 0 if false.

== Equal to
!= Not equal to
<< Less than
>> Greater than
<= Less than or equal to
>= Greater than or equal to

Logical Operators

&& Logical AND (Short-circuit)
|| Logical OR (Short-circuit)
! Logical NOT (Unary: turns truthy to 0, falsy to 1)

Examples

# Prefix math examples:
= x +2 3       # x = 2 + 3 (Evaluates to 5)
= y *10 +2 3   # y = 10 * (2 + 3) (Evaluates to 50)

# Comparisons:
= is_equal == x 5  # assigns 1 to is_equal
