Math

Evaluate a mathematical expression

# Overview

This helper outputs the result of a mathematical expression.
It uses the Mathjs library to evaluate the expression.
See examples of expressions here

The helper accepts any Mathjs expression, and also supports setting a "scope" with variables to use in the expression.

# Uses

• Use to give an LLM a calculator tool
• Use to do math calculations in a template

# Usage

Helper name : math

eg. {{#math [, optional scope]}}[expression]]{{/math}}

# LLM Usage as a calculator

This helper can be used to give an LLM a calculator tool quite effectively.
You can add an action with the name calculator and a text field called calculator_expression.
The description of the action will guide the LLM on how to use the action.
An example for the action description could be :

Use this to do mathematical calculations. You can use any expression that the javascript mathjs library supports.

You can then use the action_inject_data parameter to inject the result back into the LLM.
Here is an example that would do into the action_meta.ai_details section of an action :
