Phantom supports many different operators. Operators perform an operation between two variables or constants. The following is a list of operators that Phantom supports:

+ - Addition operator
- - Subtraction operator
* - Multiplication operator
/ - Division operator
% - Modulo operator
^ - Power operator
= - Assignment operator
& - Bit-wise AND operator
| - Bit-wise OR operator
> - Greater than operator
< - Less than operator
== - Equality operator
>= - Greater than or equal to operator
<= - Less than or equal to operator
!= - Inequality operator
&& - Logical AND operator
|| - Logical OR operator
! - Logical NOT operator

The syntax to use most operators is:

Var1 OP Var2

where,
Var1,Var2 - Variables operated on
OP - One of the operators mentioned above

The exception to this is the Logical NOT operator (!), which does not have Var1 on the left side.

The order of precedence of the operators are as follows (earlier in list is higher precedence):

1. ^
2. *,/,%
3. +,-
4. <,>,!,>=,<=,!=
5. &,|,&&,||
6. =,==

Operators with a higher precedence are performed before operators with a lower precedence. If a line contains operators with the same precedence, the operators with the same precedence will be performed from left to right. Statements placed in parentheses '()' are moved to the highest precedence.

Not all variable types support all operators. To see if a variable type supports an operator, see the Variables section.

Example Code

int i; bool b; # Assignment operator i = 10; disp(i); # Plus operator i = 3 + 6; disp(i); # Multiply operator i = 4 * 8; disp(i); # Power operator i = 4^3; disp(i); # Modulo operator i = 6 % 4; disp(i); # Bitwise OR operator i = 4 | 1; disp(i); # Bitwise AND operator i = 4 & 1; disp(i); # Logical NOT operator b = !0; disp(b); # Logical AND operator b = 1 && 5; disp(b); # Equality operator b = (i==10); disp(b); # Inequality operator b = (i!=10); disp(b); # Greater than operator b = (i>20); disp(b); # Precedence example # This gives 12 i = 2*4 + 16/2^2; disp(i); # Changing precedence using () # This gives 288 i = 2*(4+16/2)^2; disp(i);
