Converts a decimal number to signed binary format.

`DEC2BIN("100",8)`

`DEC2BIN(A2)`

`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.

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; 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.
