Either group the thousands in a four-digit number or do not, but not mixed use in the same article. However, grouping by threes and fives may coexist. Four-digit page numbers and four-digit calendar years should never be grouped (not sailed in 1,492 , but dynasty collapsed around 10,400 BC or by 13 727 AD , Vega will be the northern pole star ).
Excel's storage of numbers in binary format also affects its accuracy. [3] To illustrate, the lower figure tabulates the simple addition 1 + x − 1 for several values of x.

For example, if the threshold value for the first digit is b (i.e. 1) then a (i.e. 0) marks the end of the number (it has just one digit), so in numbers of more than one digit, first-digit range is only b–9 (i.e. 1–35), therefore the weight b 1 is 35 instead of 36.
