() 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...

integers is rounded to the nearest even integer.对于近似值的数字,返回结果取决于C库。在许多系统中,这意味着ROUND()使用”舍入最接近的偶数“规则:一个值的小数部分正好在两个整数中间时,舍入到最接近的偶数。解答根据以上规则,我们可以推断,MySQL自动将‘1.3225’这个字符串转换为了一个近似值数字。 那么,在...

The exact value number rounding makes use of the round to nearest rule. That is when the fractional part consists of a digit five or greater after the digit up to which the value will be round. The value is rounded up to the next integer value if the number is positive, while in the...
The CEILING function, orCEIL, rounds a number up to the nearest integer or specified precision. CEILING always rounds up, unlikeROUND, which rounds to the nearest value. For example:CEILING(2.3)returns 3. This function particularly helps where you need to ensure that the rounded value is not...
