# BIN2OCT function: Description, Usage, Syntax, Examples and Explanation

## What is BIN2OCT function in Excel?

BIN2OCT function is one of Engineering functions in Microsoft Excel that converts a binary number to octal.

## Syntax of BIN2OCT function

BIN2OCT(number, [places])

The BIN2OCT function syntax has the following arguments:

**Number:**The binary number you want to convert. Number cannot contain more than 10 characters (10 bits). The most significant bit of number is the sign bit. The remaining 9 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, BIN2OCT uses the minimum number of characters necessary. Places is useful for padding the return value with leading 0s (zeros).

## BIN2OCT formula explanation

- If number is not a valid binary number, or if number contains more than 10 characters (10 bits), BIN2OCT returns the #NUM! error value.
- If number is negative, BIN2OCT ignores places and returns a 10-character octal number.
- If BIN2OCT requires more than places characters, it returns the #NUM! error value.
- If places is not an integer, it is truncated.
- If places is nonnumeric, BIN2OCT returns the #VALUE! error value.
- If places is negative, BIN2OCT returns the #NUM! error value.
