* valid place values are ignored and DEC2BIN returns a 10-character
* (10-bit) binary number in which the most significant bit is the sign
* bit. The remaining 9 bits are magnitude bits. Negative numbers are
* represented using two's-complement notation.
* If number < -512 or if number > 511, DEC2BIN returns the #NUM! error
* value.
* If number is nonnumeric, DEC2BIN returns the #VALUE! error value.
* If DEC2BIN requires more than places characters, it returns the #NUM!
* error value.
* Or can be an array of values
* @param array|int $places The number of characters to use. If places is omitted, DEC2BIN uses
* the minimum number of characters necessary. Places is useful for
* padding the return value with leading 0s (zeros).
* If places is not an integer, it is truncated.
* If places is nonnumeric, DEC2BIN returns the #VALUE! error value.
* If places is zero or negative, DEC2BIN returns the #NUM! error value.
* Or can be an array of values

* @return array|string Result, or an error
* If an array of numbers is passed as an argument, then the returned result will also be an array
