Matters needing attention in this paper:

1, with a mantissa of "0", can be rewritten as numbers in units of 10,000 and 100 million. Under normal circumstances, it is not allowed to take ten, hundreds, thousands, hundreds of thousands, millions, tens of millions, billions, billions, billions, etc. As a unit (except for prefixes of hundreds, thousands and trillions). For example, 1 800 000 can be written as1800 000; 142 500 can be written as 142500, but not as142 500; 5000 words can't be written as 5000 words.

2. Pure decimal must be located by writing "0" before decimal point. The "0" at the end of the significant digits of the numerical value cannot be omitted, and it should be written in full. For example, 1.500,1.750,2.000 can't be written 1.5,1.75,2.

3. The numerical value is modified according to GB 8 170- 1987 "Rules for Numerical Value Modification", and its concise formula is "4-6 enters 5 to see the right, after 5, there are numbers up, mantissa is 0 to see the left, and left numbers are odd to enter even and discarded". For example, round to the decimal point 1 bit, 12. 149 round to12.1; 12. 169 was changed to12.2; 12. 150 is about 12.2, 12.250 is about 12.2.
