The correct format of writing numbers

The correct format for writing numbers is as follows:

The correct format of numbers may be different in different occasions and fields, but the following are some general rules for writing numbers: when writing integers, pay attention to the alignment and up-and-down alignment of numbers. For example, 12345 should be written as 12345 or 000 12345.

The decimal point should be written on the dividing line between the integer and the decimal part, and you can't click it at will. For example, 0. 123 should be written as 0. 123 instead of 123 or 0. 123. The integer part, decimal part and decimal point of decimal should be written separately, and cannot be crowded together. For example, 3.4 should be written as 3.4, not 3, 4 or 3-4.

Integer or decimal with "0" should be written in the position of "0" and cannot be omitted. For example, 120 should be written as 120.0 instead of 12 or 12.0. When the last bit of the integer part is "0", it can be omitted, but the last bit of the decimal part must be written. For example, 105 should be written as 105.0 instead of 15.

Inserting "0" between integer parts or decimal parts of numbers should follow the principle of "outside first, then inside" and cannot be inserted at will. For example, 1005 should be written as 1005.00 instead of 105.0 or10,05. For numbers with large digits, scientific notation can be used to express them so as to make it easier to write and read. For example, 123456789 should be written as 1.45789× 10 8.

When writing numbers, you should not use hyphens or other special symbols to separate numbers. For example: spelling error: 1-2-3 should be written as 123.

When writing numbers, pay attention to keeping them neat and clear, not too compact or too scattered. For example, the correct digital writing format is to write in the center and align it up and down.
