() 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...

On many systems, this means that ROUND() uses the “round to nearest even” rule: A value with a fractional part exactly half way between two integers is rounded to the nearest even integer. The following example shows how rounding differs for exact and approximate values: ...

For approximate-value numbers, the result depends on the C library. On many systems, this means that ROUND() 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“...

the configured value for Max Transaction Limit is not a multiple of the thread pool size, i.e. the transaction limit per thread groupthread_pool_max_transactions_limit divided by number of thread groups (thread_pool_size)is not an integer, this value is rounded up to the nearest integer. ...
Always rounds to the nearest integer with ties being rounded to the nearest even integer to mimic glibc's rint() behavior in the "round-to-nearest" FPU mode. Hardware-specific optimizations are possible (frndint on x86). Unlike this implementation, hardware will also honor the FPU rounding mo...
much larger than 22 (the maximum integer k for which we can represent 10^k exactly), we may be able to compute (d*10^k) * 10^(e-k) with just one roundoff. 3. Rather than a bit-at-a-time adjustment of the binary result in the hard case, we use floating-point ...
