@stdlib/assert-is-float64array

What is @stdlib/assert-is-float64array?

The @stdlib/assert-is-float64array npm package is used to check if a value is a Float64Array. This is useful for validating data types in JavaScript, especially when working with numerical computations and ensuring that the data structures are as expected.

What are @stdlib/assert-is-float64array's main functionalities?

Check if a value is a Float64Array

This feature allows you to check if a given value is a Float64Array. The function returns true if the value is a Float64Array and false otherwise.

const isFloat64Array = require('@stdlib/assert-is-float64array');

const arr = new Float64Array(10);
console.log(isFloat64Array(arr)); // true

const notArr = [1, 2, 3];
console.log(isFloat64Array(notArr)); // false

Other packages similar to @stdlib/assert-is-float64array

is-typedarray

The is-typedarray package provides a function to check if a value is a typed array, including Float64Array. It is more general than @stdlib/assert-is-float64array as it can check for various types of typed arrays, not just Float64Array.

typedarray-to-buffer

The typedarray-to-buffer package is used to convert a typed array to a Buffer. While it does not directly check if a value is a Float64Array, it is often used in conjunction with type-checking packages to handle typed arrays in Node.js.

arraybuffer-to-buffer

The arraybuffer-to-buffer package converts ArrayBuffer instances to Buffer instances. Similar to typedarray-to-buffer, it is used in scenarios where handling and validating typed arrays is necessary.

Test if a value is a Float64Array.

Installation

npm install @stdlib/assert-is-float64array

Usage

var isFloat64Array = require( '@stdlib/assert-is-float64array' );

isFloat64Array( value )

Tests if a value is a Float64Array.

var Float64Array = require( '@stdlib/array-float64' );

var bool = isFloat64Array( new Float64Array( 10 ) );
// returns true

bool = isFloat64Array( [] );
// 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 isFloat64Array = require( '@stdlib/assert-is-float64array' );

var bool = isFloat64Array( new Float64Array( 10 ) );
// returns true

bool = isFloat64Array( new Int8Array( 10 ) );
// returns false

bool = isFloat64Array( new Uint8Array( 10 ) );
// returns false

bool = isFloat64Array( new Uint8ClampedArray( 10 ) );
// returns false

bool = isFloat64Array( new Int16Array( 10 ) );
// returns false

bool = isFloat64Array( new Uint16Array( 10 ) );
// returns false

bool = isFloat64Array( new Int32Array( 10 ) );
// returns false

bool = isFloat64Array( new Uint32Array( 10 ) );
// returns false

bool = isFloat64Array( new Float32Array( 10 ) );
// returns false

bool = isFloat64Array( new Array( 10 ) );
// returns false

bool = isFloat64Array( {} );
// returns false

bool = isFloat64Array( null );
// returns false
