而要控制float类型的精度便是需要通过extra_float_digits参数了。 extra_float_digits取值范围为-15~3,默认是0。等于0时float4精确到6位数字,float8精确到15位数字。增大该值则会增加精确的位数,减小则会降低精度,例如设置该值为3,则float4精确到9位数字。 –float4类型: zjh@postgres=>do zjh-# $$ zjh$#...
lightdb中extra_float_digits参数可以用来控制浮点数输出的精度,其采用原生c语言的float4/float8实现,可能我们在平时使用中并不太会留意,但是显示的时候会有一些问题。 建一张表,两个字段类型分别是float和numeric,然后插入数据,如下: zjh@postgres=>createtablet1(c1float,c2 numeric);CREATETABLEzjh@postgres=>insert...
