Operators
Operators are used to perform mathematical and logical operations in the program.
- Arithmetic operators
- Comparison operators
- Assignment operators
- Logical operators
Arithmetic Operators:
It is used to perform arithmetic operations between values.
- Addition(+)
- Subtraction( -)
- Multiplication(*)
- Divide(/)
- Reminder(%)
- Floor division(//)
- Exponent(**)
Comparison Operators:
Comparison operator is used to compare two values and return boolean values true/false as result.
- Less than(<)
- Less than or equal to(<=)
- Greater than(>)
- Greater than(>=)
- Equal to(==)
- Not equal (!=)
Assignment Operators:
It is used to assign values on the right side to the left side variable.
| OPERATOR | OPERATOR | EQUIVALENT EXPRESSION(m=15) | RESULT |
|---|---|---|---|
| (=) | y=a+b | y=10+20 | 30 |
| (+=) | m+=10 | m=m+10 | 25 |
| (-=) | m-=10 | m=m-10 | 5 |
| (*=) | m*=10 | m=m*10 | 150 |
| (/=) | m/=10 | m=m/10 | 1.5 |
| (%=) | m%=10 | m=m%10 | 5 |
| (**=) | m**=10 | m=m^2 | 22.5 |
| (//=) | m//=10 | m=m//10 | 1 |
Logical Operators:
Logical operator is used to evaluate expressions and to make decisions.
| OPERATOR | MEANING | EXAMPLE | RESULT |
|---|---|---|---|
| AND | Logical and | (5<2 and="">3) | false |
| OR | Logical or | (5<2 or="">3) | true |
| NOT | Logical not | not(5>2) | true |
