Getting Started

Once MathLib-n is in your project, you can dive into its capabilities like this:

// Import the MathLib-n module
const mathlib = require("mathlib-n");

// Example usage of MathLib-n functions
const sum = mathlib.add(5, 3); // Returns 8
const product = mathlib.mul(4, 2); // Returns 8
const difference = mathlib.sub(5, 3); // Returns 2
const quotient = mathlib.div(4, 2); // Returns 2

Troubleshooting

Fixing Memory Issues

Ensure you avoid using synchronous loops like for or while loops with asynchronous memo(). Doing so can lead to memory issues. If you encounter memory problems, you can resolve them using the following command:

npm run fix-memo --prefix node_modules/mathlib-n

This command includes a helpful animation that provides insights into your current mode, status, and the number of records and trashes. You can skip the animation by pressing ctrl + c (Windows) or cmd + c (Mac).

Switching Modes

MathLib-n offers two modes: "science" and "fix" (abbreviated as sci and fix). You can also specify the number of decimal places with the "status" parameter.

To switch modes, use this command:

npm run modechanger --prefix node_modules/mathlib-n

Alternatively, you can change the mode programmatically:

const mathlib = require("mathlib-n");
mathlib.getmode(); // Get the current mode
mathlib.setmode("fix", 2); // Set the mode to "fix" with 2 decimal places

Again, the command includes an informative animation that you can skip if needed.
