推荐答案

请定义系统精度.如果您想知道浮点类型的准确性，则它们遵循IEEE标准.在Double，Float和Decimal类中将数字范围定义为标识epsilon的属性，据我所知， 基本上是发生舍入误差时，实际值与计算值之差的范围.

Please define system accuracy. If you want to know how accurate the floating point types are then they follow the IEEE standard. The numeric ranges are defined in the Double, Float and Decimal classes as properties identifying the epsilon which, in my understanding, is basically the range of difference between the real value and the calculated one when rounding errors do occur.

在所有具有相同位数的CPU上，这将是相同的值，因此，我不确定我是否对您关于CPU指令集和病毒的讨论有所了解.

AFAIK this is going to be the same value on all CPUs of the same bitness so I'm not sure I follow anything about your discussion on CPU instruction sets and viruses.
