方法名：getRoundingMode

MathContext.getRoundingMode介绍

[英]Returns the rounding mode. The rounding mode is the strategy to be used to round results.

The rounding mode is one of RoundingMode#UP, RoundingMode#DOWN, RoundingMode#CEILING, RoundingMode#FLOOR, RoundingMode#HALF_UP, RoundingMode#HALF_DOWN, RoundingMode#HALF_EVEN, or RoundingMode#UNNECESSARY.
[中]返回舍入模式。舍入模式是用于对结果进行舍入的策略。
四舍五入模式是四舍五入模式中的一种：向上、向下、天花板、地板、向上、向下、均匀或不必要。
