Advanced tools
Test if a double-precision floating-point numeric value is infinite.
@stdlib/math-base-assert-is-infinite is a utility package that provides functions to check if a given value is infinite. This can be useful in various mathematical computations and validations where you need to ensure that values are within a finite range.
Check if a value is infinite
This feature allows you to check if a given value is either positive or negative infinity. It returns `true` if the value is infinite and `false` otherwise.
const isInfinite = require('@stdlib/math-base-assert-is-infinite');
console.log(isInfinite(Infinity)); // true
console.log(isInfinite(-Infinity)); // true
console.log(isInfinite(5)); // false
console.log(isInfinite(NaN)); // falseLodash is a utility library that provides a wide range of functions for common programming tasks, including checking if a value is infinite using `_.isFinite`. While it offers more functionality than @stdlib/math-base-assert-is-infinite, it is also a larger library.
We believe in a future in which the web is a preferred environment for numerical computation. To help realize this future, we've built stdlib. stdlib is a standard library, with an emphasis on numerical and scientific computation, written in JavaScript (and C) for execution in browsers and in Node.js.
The library is fully decomposable, being architected in such a way that you can swap out and mix and match APIs and functionality to cater to your exact preferences and use cases.
When you use stdlib, you can be absolutely certain that you are using the most thorough, rigorous, well-written, studied, documented, tested, measured, and high-quality code out there.
To join us in bringing numerical computing to the web, get started by checking us out on GitHub, and please consider financially supporting stdlib. We greatly appreciate your continued support!
