HINCRBYFLOAT key field increment

自2.6.0起可用。

时间严重年夜度: O(1)

按指定增添field存储在指定职位的哈希key,并体现浮点数increment。假定增量值为负值,则效果是使散列字段值递减而不递增。假定该字段不存在,则0在推行操作之前将其设置为。假定发生以下情形之一,则会前往弱点:

  • 该字段网罗弱点类型的值(不是字符串)。

  • 以后字段内容或指定的增量弗身剖析为双精度浮点数。

华夏棋牌此敕令着实着实切行动与 INCRBYFLOAT 敕令的完全类似,请参阅 INCRBYFLOAT 文档以取得更多信息。

前往值

批量字符串回复:field增量后的值。

例子

redis>  HSET mykey field 10.50 (integer) 1 

redis>  HINCRBYFLOAT mykey field 0.1 "10.6" 

redis>  HINCRBYFLOAT mykey field -5 "5.6" 

redis>  HSET mykey field 5.0e3 (integer) 0 

redis>  HINCRBYFLOAT mykey field 2.0e2 "5200"

实验细节

华夏棋牌该敕令一直在复制链接和仅附加文件中作为 HSET 操作阻拦撒播,是以基础浮点数学完成中的差异不会成为不不合性的泉源。
