# Snippet - Executing Financial Functions

This sample snippet project demonstrates how to use a function from the appRules Financial library. 

## The appRules Financial Library

 [The appRules Financial Library](/apprules-r-documentation/platform/platform-features/actions/action-categories/actions-fields-library-financial.md) includes Microsoft Excel compatible financial functions that are accessible from the appRules Actions Editor.  

This sample project uses the ACCRINT financial function which returns the accrued interest for a security that pays periodic interest.

## Financial Function Action

Below is the definition of the function to be used in the PerformAction activity.  It includes the configuration of the properties required for calculating the accrued interest.
