Converts a signed hexadecimal number to signed binary format.

`HEX2BIN("f3",8)`

`HEX2BIN(A2)`

`HEX2BIN(signed_hexadecimal_number, [significant_digits])`

`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.

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.

- Hexadecimal digits are not case-sensitive;
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.
