示例1: multiplyByTenPow
/**
* Multiplies a number by a power of ten.
* This method is used in {@code BigDecimal} class.
* @param val the number to be multiplied
* @param exp a positive {@code long} exponent
* @return {@code val * 10<sup>exp</sup>}

* @param x an odd positive number.
* @param n the exponent by which 2 is raised.
* @return {@code x<sup>-1</sup> (mod 2<sup>n</sup>)}.
