@stdlib/constants-float64-pinf

What is @stdlib/constants-float64-pinf?

@stdlib/constants-float64-pinf is a package that provides a constant representing positive infinity for double-precision floating-point numbers (float64). This can be useful in various mathematical computations and comparisons where positive infinity is a meaningful value.

What are @stdlib/constants-float64-pinf's main functionalities?

Accessing Positive Infinity

This feature allows you to access the positive infinity constant directly from the package. It can be used in mathematical operations where positive infinity is required.

const PINF = require('@stdlib/constants-float64-pinf');
console.log(PINF); // Output: Infinity

Comparisons with Positive Infinity

This feature demonstrates how to use the positive infinity constant in comparisons. It can be useful for checking if a value has overflowed to positive infinity.

const PINF = require('@stdlib/constants-float64-pinf');
const value = 1e308 * 2;
console.log(value === PINF); // Output: true
