BIN2OCT FunctionWayne Becker20150916T06:23:51+00:00
The BIN2OCT function converts a binary number to octal.
Syntax
=BIN2OCT(number,[places])
Note: Hexadecimal (base 16), decimal (base 10), octal (base 8), and binary (base 2) are the most commonly used numeral systems in engineering and computing. Therefore, Excel has provided functions to convert numeric values to and from each of these systems.
Arguments
Argument 
Description 
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’scomplement 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)

Common Function Error(s)
Problem 
What went wrong 
#VALUE! 
Occurs if the supplied [places] argument is not recognized as a number 
#NUM! 
Occurs if either:

• 
the supplied number argument is not recognized as a binary number or contains more than 10 characters 

• 
the resulting octal number requires more places than is specified by the supplied [places] argument 

• 
the supplied [places] argument ≤ 0 

#NAME? 
Occurs when Analysis ToolPak addin is not enabled
