Preface – This post is part of the ABAP Programs series.

Sometimes, there is a need to know the power of a number provided by user. In that case we program to calculate power of number in ABAP. It is not a question that is merely asked in an interview but an important keyword that is used in day to day programming.

## Introduction

To calculate power of a number, you need to multiply that number by itself n times. Here n is the power. To achieve this thing we need to use Loops in ABAP. Following program implements the same:

## ABAP Program

PARAMETERS: lv_data1(10) type i, lv_data2(10) type i. While lv_data2 > 1 . lv_data1 = lv_data1 * lv_data1. lv_data2 = lv_data2 - 1. ENDWHILE. Write: lv_data1.

## Explanation

In the program, mentioned above, we have implemented a while loop to get the required result. The same is explained below, step by step:

- Initially, we have defined two parameters: lv_data1 and lv_data2. Both of these parameters are of type
**i**i.e. integer and length 10. These parameters will be used to take the number (also called base number) and the power ( also called exponent of power). - Then, we will use a while loop which will run from the power value to 1.
- We will keep multiplying the number with itself till the loop runs.
- In this line, we will keep decreasing the value of power till it is equal to 1.
- Now, we have calculated the power of the number. The output will be then printed using ABAP keyword “WRITE”.
