vCalc's Equation Editor and Constant Editor allow you to select from the library of vCalc equations, constants and data sets and to drag-and-drop these tokens1 into your equation's code or your constant's code. You can thus use anything that exists in vCalc to create something new and/or more powerful.
This page discusses some of the tokens that have been produced with the specific intent to be used as Equations-in-Equations (EiEs). These equations do something that might be used frequently in other equations or constants and used as EiEs they are time-saving devices. These EiEs are like a re-use library of simple standard functions built into vCalc's simple Groovy-based coding environment.
Some EiEs, created as function to be used like stored sub-routines, are very simple in nature. They do something so we don;t have to re-code that part of the code. They add a functionality to an equation by simply dragging them into another equation.
Other equations are complicated but still can be used as an EiE. Sometimes it's time saving to drag in a complex equation just to change that equations inputs.
Let's explore some EiE examples.
Here are equations that generate random numbers and random selection in various forms:
