## 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

Python Compiler

import math
num = 23456
arr = [0]*50
answer = [0]*50
value = 1
count = -1
j = 0
while(num > value):
count += 1
value = math.pow(8, count);
arr[count] = value;
count -= 1
print("Octal number of 23456 (decimal) is ", end="")
for i in range(count, -1, -1):
answer[j] = math.floor(num / arr[i])
j += 1
num = num % arr[i]
for i in range(0, count+1):
print(answer[i], end="")

### Output

Octal number of 23456 (decimal) is 55640

## Converter any Given Decimal Number to Octal Number

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

### Example

Python Compiler

import math
num = int(input("Enter a Decimal Number: "));
copyNum = num
arr = [0]*50
answer = [0]*50
value = 1
count = -1
j = 0
while(copyNum > value):
count += 1
value = math.pow(8, count);
arr[count] = value;
count -= 1
for i in range(count, -1, -1):
answer[j] = math.floor(copyNum / arr[i])
j += 1
copyNum = copyNum % arr[i]
print("Octal number of %d (decimal) is " % num, end="")
for i in range(0, count+1):
print(answer[i], end="")

### Output

Enter a Decimal Number: 10
Octal number of 10 (decimal) is 12
