In a computer, the property of 0 1 is a string, and 1 is a numeric property. They occupy different bytes. The 0 1 used in the date is a complete expression, which is generally used to limit the number of characters, such as common access constraints.

The mathematical expressions in daily life pay attention to simplification, so people are more accustomed to writing 65438+ 10 month 1, just like 0. 1. There is no need to write 0. 10. If you keep decimal places, it is of course another word; I used to talk about turning fake scores into scores. In fact, the false score is easier to calculate in the calculation process, and the score is to intuitively reflect the size range of the number.
