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>}
*/

{
// PRE: exp >= 0

? multiplyByPositiveInt(val, tenPows[(int)exp])
: val.multiply(powerOf10(exp)));
}示例2: modPow2Inverse
/**
* @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>)}.
*/

}示例3: multiplyByFivePow
/**
* Multiplies a number by a power of five.
* This method is used in {@code BigDecimal} class.
* @param val the number to be multiplied
