If you need to start a word or number with a zero just add an apostrophe immediately before the zero like this '0 excel will then display the zero, however the zero is no longer recognised as a number by the software.
Empty cells are ignored completely when calculating an average in Excel. If a cell contains a zero, then it is included in the calculation of the average because zero is a number and it is relevant to include it. If you want to exclude zero values in the calculation, then you could use the AVERAGEIF and set it to only include values that are above zero.
To enter 0512 into a cell so that the zero stays, put a single quote before it, like this:'0512
A sparse matrix is an array with more zero values than non-zero values.
No. It has a value of zero.
Blank Cell
Blank Cell.
Its angle is zero degrees.
#DIV/0! Microsoft Excel displays the #DIV/0! error when a number is divided either by zero (0) or by a cell that contains no value.
It displays #DIV/0! when you try to divide a number by zero. That is because it is mathematically impossible to divide something by zero, so Excel gives you that error code to indicate that it is what you tried to do.
The reason it does that is because a zero at the beginning of a value has no effect so is not required. The value 000015 is just 15, so the zeroes are dropped. The only time you start with a zero and want it is for things that are not for calculation, such as phone numbers or codes. So the way to do it is to get Excel not to treat what you are typing in as a number, but as text. You do this by typing the single quote before the number like this: '000015 Then it will treat it as text and leave the zeroes there but won't show the single quote. You can also first format the cell(s) you want to be text and then enter the values.
A cell with zero in it, a cell that is blank and a cell that has the logical value FALSE in it will all have the numerical value zero.
