() uses the “round to nearest even” rule: A value with any fractional part is rounded to the nearest even integer. (对于近似值,则依赖于底层的C函数库在很多系统中ROUND函数会使用“取最近的偶数”的规则) 通过这两条规则,我们可以看出,由于在使用两个字段相乘的时候,最终的结果是按照float类型...

Original array: [-0.7 -1.5 -1.7 0.3 1.5 1.8 2. ] Round elements of the array to the nearest integer: [-1. -2. -2. 0. 2. 2. 2.] Explanation:numpy.rint function is used to round elements of the array to the nearest integer. The values are rounded to the nearest integer....
On many systems, this means that ROUND() uses the “round to nearest even” rule: A value with a fractional part exactly halfway between two integers is rounded to the nearest even integer. The following example shows how rounding differs for exact and approximate values: mysql> SELECT ROUND...
