Basics of Using Formulas
By setting a formula in an app, you can calculate the sum of multiple values or have a value automatically displayed according to conditions specified in a function.
This page describes the basics of using and setting up formulas.
Formula basics
It is necessary to understand the following three points when using formulas.
Formulas are entered on the settings screens of "Calculated" and "Text" fields
Formulas can be used only with "Calculated" and "Text" fields.
Use a "Calculated" field if you want the calculation result to be treated as a numeric value, or use a "Text" field if you want the result to be treated as a string value.
Field codes are used to refer to fields in a formula
A field code is a string used for identifying a field. In formulas, field codes are used to refer to other fields.
For details, refer to the following pages.
Overview of Field Codes
Fields That Can/Cannot Be Referenced in Formulas
Clicking Insert Field Code displays a list of the field codes that exist in the app you are using.
Select a field code from the list to have it entered in the Formula input field.
Formulas use functions and operators
Formulas in Kintone support half-width operators (e.g., "+", "-", "*", "/"), as well as functions.
You can use multiple operators and functions together in a single formula.
List of Operators and Functions
Clicking Insert Function displays a list of the functions you can use in Kintone.
Select a function from the list to have it entered in the Formula input field.
How to set formulas
As an example, this section walks you through setting up a formula that multiplies a unit price and quantity to produce a subtotal.
You will use "Number" fields for entering numeric values, and a "Calculated" field for displaying the calculation result.
