It is same as converting any decimal number to binary or decimal to hexadecimal. Since given number is decimal integer number, so by using above algorithm performing short division by 8 with remainder. The signature of toOctalString () method is given below: public static String toOctalString (int decimal) Let's see the simple example of converting decimal to octal in java. Decimal to Octal Converter To use this decimal to octal converter, you must type a decimal value like 245 into the left field below, and then hit the Convert button.

Q.3: Find the equivalent octal form of 105 16. So by taking the remainders in reverse order, we get the equivalent octal number. Please mail your requirement at hr@javatpoint.com.

We can convert decimal to octal in java using Integer.toOctalString() method or custom logic. This is procedure for converting an Multiple this number by 8 (8 is base of octal so multiplier here).Store the value of integer part of result in an array (it will be: 0, 1, 2, 3, 4, 5, 6, and 7 because of multiplier 8).Repeat the above two steps until the number became zero.Print the array (which will be equivalent fractional octal number of given decimal fractional number).Note that a multiplicand (here decimal fractional number) is that to be multiplied by multiplier (here base of octal, i.e., 8)Since given number is decimal fractional number, so by using above algorithm performing short multiplication by 8 with integer part.Now, write these resultant integer part, this will be approximate 0.11010 which is equivalent octal fractional number of decimal fractional 0.140869140625.This method is guessing octal number of a decimal number. How to convert a decimal number with fractional part into octal? Now, write remainder from bottom to up (in reverse order), this will be 322 which is equivalent octal number of decimal integer 210.

The signature of toOctalString() method is given below: Let's see the simple example of converting decimal to octal in java. In the number system, we come across four different types of the number system, i.e. Get hold of all the important CS Theory concepts for SDE interviews with the Please write to us at contribute@geeksforgeeks.org to report any issue with the above content.Most popular in Computer Organization & Architecture The base value of a number system determines the number of digits used to represent a numeric value. This is procedure for converting an Divide this number by 8 (8 is base of octal so divisor here).Store the remainder in an array (it will be: 0, 1, 2, 3, 4, 5, 6 or 7 because of divisor 8).Repeat the above two steps until the number is greater than zero.Print the array in reverse order (which will be equivalent octal number of given decimal number).Note that dividend (here given decimal number) is the number being divided, the divisor (here base of octal, i.e., 8) in the number by which the dividend is divided, and quotient (remaining divided decimal number) is the result of the division.Since given number is decimal integer number, so by using above algorithm performing short division by 8 with remainder.Now, write remainder from bottom to up (in reverse order), this will be 322 which is equivalent octal number of decimal integer 210.But above method can not convert fraction part of a mixed (a number with integer and fraction part) octal number.

In both cases, 8 is the base to the number system that says that target or source value format is octal.

Given a decimal number as input, we need to write a program to convert the given decimal number into equivalent octal number.

Repeat the same procedure until the given number … The decimal system is base 10 (ten symbols, 0-9, are used to represent a number) and similarly, binary is base 2, octal is base 8 and hexadecimal is base 16. Example − Convert decimal number 210 into octal number. To do that, we move the pointer to its end and insert the terminating symbol.

For example, the binary number system uses two digits 0 and 1, octal number system uses 8 digits from 0-7 and decimal number system uses 10 digits 0-9 to represent any numeric value.Below diagram shows an example of converting the decimal number 33 to equivalent octal number.Please write comments if you find anything incorrect, or you want to share more information about the topic discussed above.Attention reader!
