The Calculator module provides mathematical expression evaluation functionality for eevee.bot. It listens for messages beginning with “calc " or “c " and evaluates the provided mathematical expression using mathjs.

Features

  • Mathematical expression evaluation using mathjs
  • Support for complex mathematical operations
  • Rate limiting (5 evaluations per minute per user by default)
  • Cross-platform compatibility
  • Automatic command registration
  • Factorial operations disabled for security reasons

Usage

Send a message beginning with calc or c followed by a mathematical expression to any channel where the bot is present (providing any platform prefix if required):

  !calc 2 + 2 * 3

The bot will respond with:

  8

More complex examples:

  !calc sqrt(16) + pow(2, 3)
!c sin(pi/2)
!calc 100 / (2 * 5)

Security

Factorial operations (!) are disabled in this module to prevent potential abuse that could cause performance issues.
