### Definition of HEX2BIN

Converts a signed hexadecimal number to signed binary format.

HEX2BIN("f3",8)

HEX2BIN(A2)

### Syntax

• signed_hexadecimal_number - The signed 40-bit hexadecimal value to be converted to signed binary, provided as a string.

• The most significant bit of signed_hexadecimal_number is the sign bit; that is, negative numbers are represented in two's complement format.

• For this function, this value has a maximum of 1FF if positive, and a minimum of FFFFFFFE00 if negative.

• If signed_hexadecimal_number is provided as a valid hexadecimal number, it will automatically be converted to the appropriate string input. For example, HEX2BIN(199) and HEX2BIN("199") yield the same result: 110011001.

• 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 the most significant bit of signed_hexadecimal_number is 1; that is, if the expressed signed_hexadecimal_number is greater than or equal to 8000000000.

### Notes

• As with any hexadecimal value, only the digits 0-9 and the letters A-F are valid. Digits other than these will cause HEX2BIN to return a #NUM! error.

• Hexadecimal digits are not case-sensitive; a-f and A-F are equivalent.
• 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 HEX2BIN take into account that it is in binary. Results will be silently converted; thus if cell A2 contains 11111, the binary equivalent of hexadecimal 1F, and B2 contains a formula such as =A2+9, the result will be 11120, which is incorrect in binary calculation.
