## Excel OCT2BIN Function

### Description

The Excel OCT2BIN function converts an octal number to a binary number.

### Syntax and arguments

Formula syntax

OCT2BIN(number, [places])

Arguments

 Number: Required, the octal number that needs to be converted to a binary number. The number may not contain more than 10 characters (30-bits). The most significant bits of the number indicates if the number is positive or negative, the remaining bits indicate the magnitude of the number. Negative numbers are represented using two’s-complement notation. Places: Optional, the number that specifies the number of characters of the result. If it is greater than the minimum, the result binary number will be padded out with leading zeros (0s), such as OCT2BIN("1",3) returns 001. If it is omitted, OCT2BIN used the minimum number of characters necessary, such as OCT2BIN(2) returns 10. If the argument number is negative, the place value will be ignored, and returns a 10-character binary number. If argument places is a decimal number, the place will be truncated to an integer.

### Return Value

The OCT2BIN function returns a binary number.

### Error

1. Return #NUM! error if one of the below states occurs:

• Argument number is > 777 or < 7777777000;
• Argument places is provided not enough for the argument number, such as OCT2BIN(“21”,2) returns #NUM!, because the correct result is 10001;
• Argument places is < = 0.

2. Return #VALUE! error if argument places is a non-numeric value.

### Version

Excel 2003 and later versions

### Usage and Examples

Example

There is a list of octal numbers placed in C4:C10, to get the corresponding binary numbers based on the places in D4:D10, please copy or enter the below formula to the next cell of the range:

=OCT2BIN(C4,D4)

Press Enter key and drag the auto-fill handle down to get all binary numbers.

If you just use the formula once, you also can directly type arguments in the formula:

=OCT2BIN(0,1)
