bigdicmal除法精度设置_关于BigDecimal.divide()的精度问题

网上随便一搜,是这么写的:

ROUND_CEILING

Rounding mode to round towards positive infinity.

向正无穷方向舍入

ROUND_DOWN

Rounding mode to round towards zero.

向零方向舍入

ROUND_FLOOR

Rounding mode to round towards negative infinity.

向负无穷方向舍入

ROUND_HALF_DOWN

Rounding mode to round towards "nearest neighbor" unless both neighbors are equidistant, in which case round down.

向(距离)最近的一边舍入,除非两边(的距离)是相等,如果是这样,向下舍入, 例如1.55 保留一位小数结果为1.5

ROUND_HALF_EVEN

Rounding mode to round towards the "nearest neighbor" unless both neighbors are equidistant, in which case, round towards the even neighbor.

向(距离)最近的一边舍入,除非两边(的距离)是相等,如果是这样,如果保留位数是奇数,使用ROUND_HALF_UP ,如果是偶数,使用ROUND_HALF_DOWN

ROUND_HALF_UP

Rounding mode to round towards "nearest neighbor" unless both neighbo
