In this section, you will look at some of the most common functions that work with numeric arguments. Numeric functions will help in cases where you might need to select the smallest value from the given list of values and process accordingly or convert the string representation of the given value to a number to perform some arithmetic operations using the same. It will be clearer once you go through the different functions supported by Terraform with sample inputs.
The examples used in this section will be available with the filename 1. numeric-functions.txt in the GitHub link provided at the start of this chapter. You just need to take the specific command and try it with your sample inputs in the terraform console terminal.
