Why do the formulas in Excel sometimes calculate inaccuracies and calculate error values?
In general, the use of formula functions, as long as the attention to two aspects of the problem, should not have any problems.
One is to use a pair function. Each function has its own name, and each function has its own calculation function. Therefore, the use of the name of the function is to ensure that the calculation does not problem the first pass.
