DEC2BIN

The DEC2BIN function converts a decimal number to signed binary format.

Sample Usage

DEC2BIN("100",8)

DEC2BIN(A2)

Syntax

DEC2BIN(decimal_number, [significant_digits])

• decimal_number - The decimal value to be converted to signed binary, provided as a string.

  • For this function, this value has a maximum of 511 if positive, and a minimum of -512 if negative.
  • If decimal_number is provided as a valid decimal number, it will automatically be converted to the appropriate string input. For example, DEC2BIN(199) and DEC2BIN("199") yield the same result: 11000111.

• significant_digits - [ OPTIONAL ] The number of significant digits to ensure in the result.

  • If this is greater than the number of significant digits in the result, the result is left-padded with zeros until the total number of digits reaches significant_digits.
  • This value is ignored if decimal_number is negative.

Notes

• If the number of digits required is greater than the specified significant_digits, the #NUM! error is returned.
• Ensure that any calculations using the result of DEC2BIN take into account that it is in binary. Results will be silently converted by Google Sheets; thus if cell A2 contains 11111, the binary equivalent of the decimal value 31, and B2 contains a formula such as =A2+9, the result will be 11120, which is incorrect in binary calculation.
