Format Cells

Hello all,


In Excel 2010 there are many formats for cells in Home > number group > drop-down list. And also by Format Cells dialog box.
My question is, why we use those formats? Is there any benefit for it please?

Yes, to give you different ways of presenting those numbers, as a percentage, as a date, as currency, and so on. Odd question!

OK. Thanks for the answer.
