The OCT2BIN function in Google Sheets is a powerful tool for converting signed octal numbers into signed binary format. This function is essential for those working with octal numeral systems, enabling seamless transition between octal and binary representations, which is particularly useful in computer science and digital electronics contexts.

Syntax

OCT2BIN(number, [places])

• number: The signed octal number you want to convert. It must be within the range of -512 to 511.
• places: (Optional) This specifies the number of bits to be used in the output binary number. If omitted, the default is 10 bits.

Example #1

OCT2BIN(17)

This function converts the octal number 17 into binary format. The result is 011111, representing the decimal value 15.

Example #2

OCT2BIN(-10)

This call converts the octal number -10 to binary. The output is 11111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111110000 in a 10-bit format, indicating a negative binary value.

Example #3

OCT2BIN(8, 6)

Here, the octal number 8 is converted to a binary representation using 6 bits. The result is 001000, corresponding to the decimal value 8.

Error handling

• NUM!: This error occurs if the input number is outside the valid range of -512 to 511.
• VALUE!: This indicates that the input value is not a valid octal number. Make sure to enter valid octal digits (0-7).
• REF!: This error means that the formula references an invalid cell. Double-check the cell references used in the function.

Conclusion

The OCT2BIN function is invaluable for professionals dealing with number conversions, especially in technical fields such as computing and electronics. Its straightforward syntax and practical applications streamline the conversion process, making it an essential tool for precise calculations and data analysis in Google Sheets.
