这篇博客详细介绍了SAP ABAP中的四种操作符类别：算术操作符、比较操作符、位操作符和字符字符串操作符。通过示例展示了它们在不同场景下的用法，包括自动类型转换规则和各种比较操作符的使用。

ABAP provides a rich set of operators to manipulate variables. All ABAP operators are classified into four categories −

Arithmetic Operators
Comparison Operators
Bitwise Operators
Character String Operators

Arithmetic Operators

Arithmetic operators are used in mathematical expressions in the same way that they are used in algebra. The following list describes arithmetic operators. Assume integer variable A holds 20 and variable B holds 40.

S.No.	Arithmetic Operator & Description
1	+ (Addition) Adds values on either side of the operator. Example: A + B will give 60.
2	− (Subtraction) Subtracts right hand operand from left hand operand. Example: A − B will give -20.
3	* (Multiplication) Multiplies values on either side of the operator. Example: A * B will give 800.
4	/ (Division) Divides left hand operand by right hand operand. Example: B / A will give 2.
5	MOD (Modulus) Divides left hand operand by right hand operand and returns the remainder. Example: B MOD A will give 0.

Example

REPORT YS_SEP_08. 
DATA: A TYPE I VALUE 150, 
B TYPE I VALUE 50, 
Result TYPE I. 
Result =  A / B. 
WRITE / Result.

The above code produces the following output −

Comparison Operators

Let’s discuss the various types of comparison operators for different operands.

S.No.	Comparison Operator & Description
1	= (equality test). Alternate form is EQ. Checks if the values of two operands are equal or not, if yes then condition becomes true. Example (A = B) is not true.
2	<> (Inequality test). Alternate form is NE. Checks if the values of two operands are equal or not. If the values are no

S.No.

Comparison Operator & Description

= (equality test). Alternate form is EQ.

Checks if the values of two operands are equal or not, if yes then condition becomes true. Example (A = B) is not true.

<> (Inequality test). Alternate form is NE.

Checks if the values of two operands are equal or not. If the values are no
