BC is short for Binary calculator. BC * function parameters are all operands plus an optional [int scale], such as string bcadd (string $ left_operand, string $ right_operand [, int $ scale]). If scale is not provided, use the default value of bcscale. Here, the large number is represented by a string consisting of 0-9, and the return value is also a string.
