How to use DEC2OCT Function in Excel

The Excel DEC2OCT function converts a decimal number to its octal equivalent.

Syntax: =DEC2OCT (number, [places])

The DEC2OCT function syntax has the following arguments:

  • Number    Required. The decimal integer you want to convert. If number is negative, places is ignored and DEC2OCT returns a 10-character (30-bit) octal number in which the most significant bit is the sign bit. The remaining 29 bits are magnitude bits. Negative numbers are represented using two’s-complement notation.
  • Places    Optional. The number of characters to use. If places is omitted, DEC2OCT uses the minimum number of characters necessary. Places is useful for padding the return value with leading 0s (zeros).

Example: Let’s look at some Excel DEC2OCT function examples and explore how to use the DEC2OCT function as a worksheet function in Microsoft Excel:

Result: 144

Syntax: =DEC2OCT(A4)
Result: 37

Syntax: =DEC2OCT(A5)
Result: 7777777770

Syntax: =DEC2OCT(A6)
Result: 310

Syntax: =DEC2OCT(A7)
Result: 1

Syntax: =DEC2OCT(A8)
Result: 3777777777

Syntax: =DEC2OCT(A9)
Result: #NUM!

Syntax: =DEC2OCT(A10)
Result: 257741

Syntax: =DEC2OCT(A11,B11)
Result: 072

Syntax: =DEC2OCT(A12,B12)
Result: 0000000010

Syntax: =DEC2OCT(A13,B13)
Result: 011

Syntax: =DEC2OCT(A14,B14)
Result: 0031

Syntax: =DEC2OCT(A15,B15)
Result: 00000016

Note:

  1. If number < -536,870,912 or if number > 536,870,911, DEC2OCT returns the #NUM! error value.
  2. If number is nonnumeric, DEC2OCT returns the #VALUE! error value.
  3. If DEC2OCT requires more than places characters, it returns the #NUM! error value.
  4. If places is not an integer, it is truncated.
  5. If places is nonnumeric, DEC2OCT returns the #VALUE! error value.
  6. If places is negative, DEC2OCT returns the #NUM! error value.
