Glossary Item Box

In many of the cell types, users can type in a formula by simply starting with an equals sign (=). No special property needs to be set to allow this. How the result is displayed depends on the cell type. For example, an integer cell type displays the result as an integer, even if the result of the formula is not an integer. In this case, a number may appear rounded. For currency and date cells, specific formatting can be defined. For more information on setting various cell types, refer to Working with Editable Cell Types.

For information on the floating formula bar, where users can type in formulas and select cells dynamically, refer to Setting up the Formula Text Box.
