The calculation of the decimal point in the Excel cell is always a headache.
If there are three decimal places, now only two decimal points, then there will certainly be rounding the problem, so, in the calculation, the results of the precision is not high.
Another situation is that, given the number of bits of data display, in the event of discarding a part of the decimal point, only one or two decimal points, then, in the calculation, the accuracy is not high.
Simple point is: How to eliminate the calculation error after the reduction, sometimes we entered the number is the second decimal point, but in the precision requirements of only one, the indentation after the display is no problem, but the results of the calculation is error.
The workaround is: click tools → options → recalculate
Select "To display values as" (), so that the results are not error.
Error analysis of computational accuracy:
In fact, it is not an error in the calculation, but a rounding of the display settings.
The method provided by this technique can solve the problem in the display, but at the same time it will change the precision of the numerical value, and Excel will give you a warning before using it.
