Calculator Plugin Documentation

The Calculator is a powerful tool built on Math.js, offering quick and advanced mathematical computations. It supports a wide range of features, from simple arithmetic to unit conversions and variable handling.

Features

1. Perform Advanced Calculations

Use the calculator to handle:

• Basic arithmetic: 5 + 3, 12 / 4
• Trigonometry: sin(30°), cos(pi/3)
• Statistics: mean(5, 10, 15), std(4, 7, 9)
• Complex numbers: 2 + 3i, abs(3 + 4i)
• And more advanced mathematical functions provided by Math.js.

2. Work with Variables

• Assign variables within calculations, e.g., x = 5, y = x * 2.
• Refer to the last result using ans. For example:

  5 * 2  
  ans + 3  
  

• Access specific results using $<number> notation, where <number> corresponds to the calculation’s position in the history. For example:

  $3 * 2  
  

  (Fetches the result from the third calculation.)

3. Modify Previous Calculations

Easily revisit and adjust past calculations by clicking on them in the history. This allows you to refine inputs and recalculate effortlessly.

4. Convert Between Units

Seamlessly convert between various units of measurement. Examples include:

• Length: 5 cm to inches
• Weight: 10 kg to pounds
• Time: 2 hours to minutes
• Temperature: 100 °C to °F
• Volume: 1 liter to gallons

5. Interactive Interface

• Calculation history is preserved, making it easy to track and reuse results.
• The plugin highlights errors and offers suggestions for corrections.
