包路径：java.math.BigDecimal
类名称：BigDecimal
方法名：movePointLeft

BigDecimal.movePointLeft介绍

[英]Returns a new BigDecimal instance where the decimal point has been moved n places to the left. If n < 0 then the decimal point is moved -n places to the right.

The result is obtained by changing its scale. If the scale of the result becomes negative, then its precision is increased such that the scale is zero.

Note, that movePointLeft(0) returns a result which is mathematically equivalent, but which has scale >= 0.
[中]返回一个新的BigDecimal实例，其中小数点已向左移动n位。如果n<0，则小数点向右移动-n位。
结果是通过改变其比例得到的。如果结果的刻度变为负值，则其精度将增加，使刻度为零。
请注意，movePointLeft（0）返回的结果在数学上是等价的，但其比例>=0。
