# WorksheetFunction.Oct2Bin (Excel)

Converts an octal number to binary.

If number is negative, Oct2Bin ignores places and returns a 10-character binary number. If number is negative, it cannot be less than 7777777000, and if number is positive, it cannot be greater than 777. If number is not a valid octal number, Oct2Bin returns the #NUM! error value. If Oct2Bin requires more than places characters, it returns the #NUM! error value. If places is not an integer, it is truncated. If places is nonnumeric, Oct2Bin returns the #VALUE! error value. If places is negative, Oct2Bin returns the #NUM! error value.

**Oct2Bin** (Arg1, Arg2)

```
Dim strOct2Bin As String
strOct2Bin = WorksheetFunction.Oct2Bin(Arg1:=)
```

## Arguments

Arg1, Arg2Arg1 - Number - the octal number that you want to convert. Number may not contain more than 10 characters. The most significant bit of number is the sign bit. The remaining 29 bits are magnitude bits. Negative numbers are represented using two's-complement notation

Arg2 - Places - the number of characters to use. If places is omitted, Oct2Bin uses the minimum number of characters necessary. Places is useful for padding the return value with leading 0s (zeros)
