Basic Usage of Formulas
In kintone, you can use formulas.
You set formulas in the Calculated field or the Text field. In formulas, you can use values of other fields.
When you set formulas, you must use field codes as described below.
2. In the Calculated field or the Text field, specify an formula that includes the field code.
Example of displaying the result of the unit price multiplied by the quantity: In the above example, two Number fields ("Unit Price" and "Quantity") and two field codes ("Unit_Price" and "Quantity") are set in the app form. Then, the formula "Unit_Price*Quantity" is set in the Calculated field.
This section describes the way to set a formula, by using an example of an order management app.
You use the Number field to enter a number, and the Calculated field to display result.
