This book enables you to create your own simple or medium to complex hybrid apps for business or personal use. As a beginner to AppSheet, this book will show you how the AppSheet Editor works and how it is used to configure, test, and deploy an app and share it with others as users or co-authors. You’ll learn about widely used features such as how to use data sources, create app views and actions, construct expressions with AppSheet functions, and make your app secure through security and UX options. Next, you’ll create email/attachment templates and develop reports/documents based on templates, store in the cloud, and send files through emails. You’ll also understand how to integrate third-party services and monitor various usage statistics of your app. As you progress, you’ll explore various features with the help of sample apps that you create using the book.

Performing arithmetic calculations with math functions and expressions

We will learn about the most used math functions in this section. Math functions are mostly useful in numerical calculations and data presentations. You may want to show the user a rounded-off distance value, in kilometers, as an integer, rather than the calculated distance with decimals. You can achieve this using math functions and expressions:

Table 4.23 – Math functions – FLOOR(), CEILING(), and ROUND()

Let us next learn how to use the MOD() function to find the arithmetic remainder when we divide one integer by another:

Table 4.24 – Math function of MOD()

Let us next learn about the SUM() function, which adds all the values in a numerical-type list:

Table 4.25 – SUM() function

At times, you want to compute a random number within a number range. You can use the RANDBETWEEN() function to compute a random integer...
