@stdlib/assert-is-float32array

What is @stdlib/assert-is-float32array?

The @stdlib/assert-is-float32array package provides utilities to check if a value is a Float32Array. This can be useful in various scenarios where type checking is necessary, such as validating function inputs or ensuring data integrity.

What are @stdlib/assert-is-float32array's main functionalities?

Check if a value is a Float32Array

This feature allows you to check if a given value is a Float32Array. The function returns true if the value is a Float32Array and false otherwise.

const isFloat32Array = require('@stdlib/assert-is-float32array');

const arr = new Float32Array(10);
console.log(isFloat32Array(arr)); // true

const notArr = [1, 2, 3];
console.log(isFloat32Array(notArr)); // false

Other packages similar to @stdlib/assert-is-float32array

is-typedarray

The is-typedarray package provides a utility to check if a value is a typed array, including Float32Array. It is more general than @stdlib/assert-is-float32array as it can check for various types of typed arrays, not just Float32Array.

typedarray-to-buffer

The typedarray-to-buffer package converts typed arrays to Node.js Buffer objects. While it does not directly check if a value is a Float32Array, it operates on typed arrays and can be used in conjunction with type-checking utilities.

About stdlib...

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!

isFloat32Array

Test if a value is a Float32Array.

Installation

npm install @stdlib/assert-is-float32array

Usage

var isFloat32Array = require( '@stdlib/assert-is-float32array' );

isFloat32Array( value )

Tests if a value is a Float32Array.

var Float32Array = require( '@stdlib/array-float32' );

var bool = isFloat32Array( new Float32Array( 10 ) );
// returns true

bool = isFloat32Array( [] );
// returns false

Examples

var Int8Array = require( '@stdlib/array-int8' );
var Uint8Array = require( '@stdlib/array-uint8' );
var Uint8ClampedArray = require( '@stdlib/array-uint8c' );
var Int16Array = require( '@stdlib/array-int16' );
var Uint16Array = require( '@stdlib/array-uint16' );
var Int32Array = require( '@stdlib/array-int32' );
var Uint32Array = require( '@stdlib/array-uint32' );
var Float32Array = require( '@stdlib/array-float32' );
var Float64Array = require( '@stdlib/array-float64' );
var isFloat32Array = require( '@stdlib/assert-is-float32array' );

var bool = isFloat32Array( new Float32Array( 10 ) );
// returns true

bool = isFloat32Array( new Int8Array( 10 ) );
// returns false

bool = isFloat32Array( new Uint8Array( 10 ) );
// returns false

bool = isFloat32Array( new Uint8ClampedArray( 10 ) );
// returns false

bool = isFloat32Array( new Int16Array( 10 ) );
// returns false

bool = isFloat32Array( new Uint16Array( 10 ) );
// returns false

bool = isFloat32Array( new Int32Array( 10 ) );
// returns false

bool = isFloat32Array( new Uint32Array( 10 ) );
// returns false

bool = isFloat32Array( new Float64Array( 10 ) );
// returns false

bool = isFloat32Array( new Array( 10 ) );
// returns false

bool = isFloat32Array( {} );
// returns false

bool = isFloat32Array( null );
// returns false
