Operators

Operators are symbols used to compare or assign values.

Comparison operators

==
Checks if the two values are equal. Don't confuse this with the assignment operator, which is a single equal sign.
!=
Checks if the two values are not equal.
>
Checks if the lefthand value is greater than the righthand value.
<
Checks if the lefthand value is less than the righthand value.
>=
Checks if the lefthand value is greater than or equal to the righthand value.
<=
Checks if the lefthand value is less than or equal to the righthand value.

Assignment operators

Expressions are not supported in this language; however, compound operations are available. For example, a += b is equivalent to the hypothetical statement a = a + b.

=
Assign. Sets the variable on the lefthand side to the value on the righthand side. Don't confuse this with the equality comparison operator, which is two equal signs.
+=
Add-assign. Increases the variable on the lefthand side by the value on the righthand side.
-=
Subtract-assign. Decreases the variable on the lefthand side by the value on the righthand side.
*=
Multiply-assign. Multiplies the variable on the lefthand side by the value on the righthand side.
/=
Divide-assign. Divides the variable on the lefthand side by the value on the righthand side. Any remainder will be discarded.
%=
Modulo-assign. Sets the lefthand variable to the remainder of dividing the lefthand value by the righthand value.
&=
Binary-AND-assign. Modifies each bit in the variable on the lefthand side: bits will be set to zero if the corresponding bit in the righthand value is zero; otherwise, bits will be left unchanged.
|=
Binary-OR-assign. Modifies each bit in the variable on the lefthand side: bits will be set to one if the corresponding bit in the righthand value is one; otherwise, bits will be left unchanged.
^=
Binary-XOR-assign. Modifies each bit in the variable on the lefthand side: bits will be set to one if the corresponding bit in the righthand value is the same, or set to zero otherwise.
~=
Binary-NOT-assign. Modifies each bit in the variable on the lefthand side: bits will be set to zero if the corresponding bit in the righthand value is one, or left unchanged otherwise. This is equivalent to a &= ~b.
