Overview

The Calculator tool lets your agent perform mathematical calculations during a conversation. Add it from Tools → Add → Calculator.

​
Availability

  • Built-in tool with no external integration required
  • Singleton tool per agent: if one Calculator already exists, the add-menu item is disabled

​
Current Configuration

Calculator has no advanced setup form. When you add it, the tool is created with:
  • Name: Calculator
  • Description: Perform mathematical calculations
You can reopen the dialog to keep or delete the tool, but there are no extra fields to configure today.

​
Supported Calculations

The Calculator evaluates safe mathematical expressions. It supports:
  • arithmetic operators: +, -, *, /, //, %, **
  • parentheses for grouping
  • functions: abs, round, min, max, sum, sqrt, ceil, floor, log, log10, sin, cos, tan
  • constants: pi, e
There is no special percent operator. Express percentages as arithmetic, such as price * 0.2 for 20% of a price.
Calculator expressions are capped at 200 characters and do not support symbolic math, derivatives, integrals, or arbitrary code execution.
Use your prompt to tell the agent when it should rely on Calculator instead of answering from memory. 
When the caller asks for a total, discount, repayment amount, or percentage,
use the Calculator tool before answering.

Always state the result clearly and confirm the currency or units if relevant.

​
Good Use Cases

  • quoting totals after discounts or fees
  • calculating installment amounts
  • comparing percentage changes
  • converting simple pricing logic into a precise spoken answer
Use Custom Action instead if the value must come from your backend, CRM, billing system, or another source of truth.

​
Testing Checklist

  1. Add the tool in Expert Mode.
  2. Run a test conversation.
  3. Ask the agent to solve a few realistic calculations.
  4. Confirm the spoken answer matches the expected value.
  5. Check that the agent still explains the result in business language, not just raw numbers.
