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!

Constructors

Array constructors.

Installation

npm install @stdlib/array-ctors

Alternatively,

• To load the package in a website via a script tag without installation and bundlers, use the ES Module available on the esm branch (see README).
• If you are using Deno, visit the deno branch (see README for usage intructions).
• For use in Observable, or in browser/node environments, use the Universal Module Definition (UMD) build available on the umd branch (see README).

The branches.md file summarizes the available branches and displays a diagram illustrating their relationships.

To view installation and usage instructions specific to each branch build, be sure to explicitly navigate to the respective README files on each branch, as linked to above.

Usage

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

ctors( dtype )

Returns an array constructor for a specified data type.

var ctor = ctors( 'float64' );
// returns <Function>

The function returns constructors for the following data types:

• float32: single-precision floating-point numbers.
• float64: double-precision floating-point numbers.
• complex64: single-precision complex floating-point numbers.
• complex128: double-precision complex floating-point numbers.
• bool: boolean values.
• generic: values of any type.
• int16: signed 16-bit integers.
• int32: signed 32-bit integers.
• int8: signed 8-bit integers.
• uint16: unsigned 16-bit integers.
• uint32: unsigned 32-bit integers.
• uint8: unsigned 8-bit integers.
• uint8c: unsigned clamped 8-bit integers.

If provided an unknown or unsupported data type, the function returns null.

var ctor = ctors( 'float' );
// returns null

Examples

var dtypes = require( '@stdlib/array-dtypes' );
var ctors = require( '@stdlib/array-ctors' );

var DTYPES = dtypes();
var ctor;
var i;

for ( i = 0; i < DTYPES.length; i++ ) {
    ctor = ctors( DTYPES[ i ] );
    console.log( ctor );
}
