ABAP Integer Division: DIV, MOD, and Decimal Results

In SAP ABAP, integer division follows specific rules because ABAP does not support direct integer division where the result remains an integer. Instead, division in ABAP always produces a decimal result unless explicitly converted.

1. Normal Division (Decimal Result)

When dividing two integers, ABAP returns a decimal value.

DATA: lv_num1 TYPE I VALUE 10,
      lv_num2 TYPE I VALUE 3,
      lv_result TYPE F.  "Floating-point type

lv_result = lv_num1 / lv_num2.
WRITE: lv_result.  "Output: 3.3333333

2. Integer Division (Truncate Decimal Part)

To perform integer division and discard the decimal part, use DIV keyword:

DATA: lv_num1 TYPE I VALUE 10,
      lv_num2 TYPE I VALUE 3,
      lv_result TYPE I.

lv_result = lv_num1 DIV lv_num2.
WRITE: lv_result.  "Output: 3

3. Modulo (Remainder Calculation)

If you need the remainder, use MOD:

DATA: lv_remainder TYPE I.

lv_remainder = lv_num1 MOD lv_num2.
WRITE: lv_remainder.  "Output: 1

4. Using Float for Precise Division

If you want a precise result, use F (Floating-point) or P (Packed decimal) types:

DATA: lv_result TYPE P DECIMALS 2.

lv_result = lv_num1 / lv_num2.
WRITE: lv_result.  "Output: 3.33
