* DECTOBIN * * Return a decimal value as binary. * * Excel Function: * DEC2BIN(x[,places]) * * @access public * @category Engineering Functions *

Parameters

string $x The decimal integer you want to convert. If number is negative,: * 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. * @param integer $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. * @return string
