# Batch Script Operators - Batch Script

## What is Batch Script Operators?

An operator is a symbol that expresses the compiler to accomplish precise mathematical or logical manipulations.
In batch script, the resulting types of operators are possible.

• Arithmetic operators
• Relational operators
• Logical operators
• Assignment operators
• Bitwise operators

## Arithmetic Operators

Batch script language chains the normal Arithmetic operators as any language. Resulting are the Arithmetic operators available.

Show Example

 Operator Description Example + Addition of two operands 1 + 2 will give 3 − Subtracts second operand from the first 2 − 1 will give 1 * Multiplication of both operands 2 * 2 will give 4 / Division of the numerator by the denominator 3 / 2 will give 1.5 % Modulus operator and remainder of after an integer/float division 3 % 2 will give 1

## Relational Operators

Relational operators allow of the comparison of objects. Below are the relational operators available.

Show Example

 Operator Description Example EQU Tests the equality between two objects 2 EQU 2 will give true NEQ Tests the difference between two objects 3 NEQ 2 will give true LSS Checks to see if the left object is less than the right operand 2 LSS 3 will give true LEQ Checks to see if the left object is less than or equal to the right operand 2 LEQ 3 will give true GTR Checks to see if the left object is greater than the right operand 3 GTR 2 will give true GEQ Checks to see if the left object is greater than or equal to the right operand 3 GEQ 2 will give true

## Logical Operators

Logical operators are used to assess Boolean expressions. Resulting are the logical operators available.

The batch language is equipped with a full set of Boolean logic operators like AND, OR, XOR, but only for binary numbers. Neither are there any values for TRUE or FALSE. The only logical operator available for conditions is the NOT operator.

Show Example

 Operator Description AND This is the logical “and” operator OR This is the logical “or” operator NOT This is the logical “not” operator

## Assignment Operators

Batch Script language also delivers assignment operators. Resulting are the assignment operators available.

Show Example

 Operator Description Example += This adds right operand to the left operand and assigns the result to left operand Set /A a = 5 a += 3 Output will be 8 -= This subtracts the right operand from the left operand and assigns the result to the left operand Set /A a = 5 a -= 3 Output will be 2 *= This multiplies the right operand with the left operand and assigns the result to the left operand Set /A a = 5 a *= 3 Output will be 15 /= This divides the left operand with the right operand and assigns the result to the left operand Set /A a = 6 a/ = 3 Output will be 2 %= This takes modulus using two operands and assigns the result to the left operand Set /A a = 5 a% = 3 Output will be 2

## Bitwise Operators

Bitwise operators are also possible in batch script. Resulting are the operators available.

Show Example

 Operator Description & This is the bitwise “and” operator | This is the bitwise “or” operator ^ This is the bitwise “xor” or Exclusive or operator

Resulting is the truth table showcasing these operators.

 p q p & q p | q p ^ q 0 0 0 0 0 0 1 0 1 1 1 1 1 1 0 1 0 0 1 1
