方法名：scaleByPowerOfTen

BigDecimal.scaleByPowerOfTen介绍

[英]Returns a new BigDecimal whose value is this * 10n. The scale of the result is this.scale() - n. The precision of the result is the precision of this.

This method has the same effect as #movePointRight, except that the precision is not changed.
[中]返回一个新的BigDecimal，其值为*10n。结果的规模是这样的。scale（）-n。结果的精度就是这个的精度。
此方法的效果与#movePointRight相同，只是精度没有改变。
