Operator Precedence
What is the precedence of the operators or calculation in an expression?
Which calculation or operation will be executed first division or addition?
Explanation
Operators Execution Order:
When the expression or the formula has more operators they will follow the following order of precedence.
Say we have an expression a = 4*2+4;.
Here as we can note from the table. Operator "*" (multiplication) has top preference than "=" (equals) and "+" (addition), so 4*2 will be executed first.
Now the expression is a = 8+4;
In this "+" has highest preference so addition will be done. The result is equated to a and so a becomes 12.
When the expression or the formula has more operators they will follow the following order of precedence.
| Precedence Order | Operator (Symbol) | Operator in Words |
| 1 | !, ++, --, ~ | Not, Increment, Decrement |
| 2 | *, /, %, +, - | Multiplication, Division, Modulus, Addition, Subtraction |
| 3 | << , >>, >>> | - |
| 4 | <, <=, >, >= | Less Than, Less than or equal to, Greater Than, Greater than or equal to |
| 5 | ==, !=, ===, !== | Equals Comparison, Not Equals, Strictly Equals, Strictly Not Equals |
| 6 | &, |, ^, &&, || | Bitwise AND, Bitwise OR, Bitwise Exclusive OR, Logical AND, Logical OR |
| 7 | ?: | Ternary Operator |
| 8 | Assignment Operators =, +=, -=, /=, *=, %=, <<=, >>=, >>>=, &=, ^= | Assign, other assignment operators |
