What effect does the decrease decimal button have on selected cells?

The decrease decimal button is designed to reduce the number of decimal places displayed in selected cells of a spreadsheet. When this button is used, it effectively shifts the decimal point to the left, which means that if the cell contained a number with several decimal places, those places will be decreased one at a time with each click of the button. For example, if a cell displays the number 3.456 and the decrease decimal button is used repeatedly, the display will change to 3.45, then 3.4, and so on, until it eventually shows a whole number like 3.

This function is particularly useful in financial spreadsheets, where numbers often need to be presented in a more rounded format for clarity or to fit standard reporting practices. By shifting the decimal point and thus reducing the precision of the number displayed, users can tailor the information to better suit their needs without altering the actual value stored in the cell.
