Flux includes a powerful calculator tool that allows you to evaluate mathematical expressions and perform engineering calculations directly from the chat interface. This tool helps you quickly solve equations without having to switch to a separate calculator application.
Overview
The calculator tool enables you to:
Evaluate mathematical expressions of varying complexity
Perform engineering calculations relevant to circuit design
Work with arrays and matrices for more complex operations
Get results in a clear, formatted output
Extract and evaluate equations from datasheets
How to Use the Calculator Tool
To evaluate mathematical expressions using Flux, use the @calculator tool in your query:
When you use the @calculator tool, Flux will:
Parse the mathematical expression
Check for any undefined variables or functions
Evaluate the expression using the mathjs library
Return the result in a formatted output
Supported Operations
The calculator tool supports a wide range of mathematical operations:
Basic Arithmetic
Addition, subtraction, multiplication, division
Exponentiation and square roots
Modulo and integer division
Trigonometric Functions
Sine, cosine, tangent (and their inverses)
Support for both radians and degrees (using
degsuffix)
Logarithmic and Exponential Functions
Natural logarithm (ln) and base-10 logarithm (log10)
Exponential function (exp)
Engineering Functions
Unit conversions (e.g., ohms to kilohms)
Engineering notation (e.g., 1k = 1000)
Complex number operations
Matrix and Array Operations
Matrix creation and manipulation
Vector operations
Array indexing and slicing
Example Calculations
Here are some examples of how you can use the calculator tool:
Circuit Calculations
Power and Energy Calculations
Timing and Frequency Calculations
Result Formatting
The calculator tool formats results based on the type of calculation:
Scalar Values
Simple numerical results are displayed with appropriate precision and units when applicable.
Arrays and Vectors
One-dimensional arrays are displayed in a tabular format with index and value columns.
Matrices
Two-dimensional arrays (matrices) are displayed in a tabular format with row indices and values.
Complex Numbers
Complex numbers are displayed in the form a + bi where a is the real part and b is the imaginary part.
Tips for Effective Calculations
To get the most out of the calculator tool:
Use engineering notation - You can use suffixes like k, M, m, u, n, p (e.g., 10k for 10,000 or 1u for 0.000001).
Include units for clarity - While not required for calculation, adding units like V, A, or ohm helps with readability.
Use parentheses for complex expressions - Ensure correct order of operations by using parentheses in complex expressions.
Break down complex calculations - For very complex calculations, consider breaking them into smaller steps.
Extracting Equations from Datasheets
A powerful feature of the calculator tool is its ability to extract and evaluate equations from datasheets:
Attach a datasheet to your chat
Use the
@calculatortool to reference an equation in the datasheetProvide the values for the variables in the equation
For example:
Limitations
While the calculator tool is powerful, it has some limitations to be aware of:
The tool cannot evaluate expressions with undefined variables
Very complex mathematical operations might require breaking down into simpler steps
The tool does not support solving equations (finding x where f(x) = 0)
Some specialized engineering functions might not be available
The tool does not maintain state between calculations
