Converter a Number from Decimal to Octal

In the following example, we will convert a Decimal Number (100) to Octal Number (144).

Tips: It is recommended to use our online Decimal to Octal calculator for better understanding.

Example

C# Compiler
using System; namespace myApp { class Program { static void Main(string[] args) { int num = 23456; int[] arr = new int[50]; int[] answer = new int[50]; int value = 1; int i, j = 0; int count = -1; while(num > value) { count++; value = (int) Math.Pow(8, count); arr[count] = value; } count = count - 1; for(i=count; i>=0; i--) { answer[j] = num / arr[i]; j++; num = num % arr[i]; } Console.Write("Octal number of 23456 (decimal) is "); for(i=0; i<=count; i++) Console.Write(answer[i]); } } }

Converter any Given Decimal Number to Octal Number

In the following example, we will convert any given decimal number to an octal number.

Example

C# Compiler
using System; namespace myApp { class Program { static void Main(string[] args) { int num, copyNum; int[] arr = new int[50]; int[] answer = new int[50]; int value = 1; int i, j = 0; int count = -1; Console.Write("Enter a Decimal number: "); num = Convert.ToInt32(Console.ReadLine()); copyNum = num; while(copyNum > value) { count++; value = (int) Math.Pow(8, count); arr[count] = value; } count = count - 1; for(i=count; i>=0; i--) { answer[j] = copyNum / arr[i]; j++; copyNum = copyNum % arr[i]; } Console.Write("Octal number of {0} (decimal) is ", num); for(i=0; i<=count; i++) Console.Write(answer[i]); } } }
