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!

array2dtype

Return the WebAssembly data type for a provided array.

Installation

npm install @stdlib/wasm-base-array2dtype

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 array2dtype = require( '@stdlib/wasm-base-array2dtype' );

array2dtype( array )

Returns the WebAssembly data type for a provided array.

var Float64Array = require( '@stdlib/array-float64' );
var arr = new Float64Array( 10 );

var dt = array2dtype( arr );
// returns 'float64'

If provided an argument having "generic" or an unknown/unsupported data type, the function assumes that array values can be stored as double-precision floating-point numbers and returns 'float64'.

var dt = array2dtype( [] );
// returns 'float64'

Examples

var dtypes = require( '@stdlib/array-dtypes' );
var empty = require( '@stdlib/array-empty' );
var array2dtype = require( '@stdlib/wasm-base-array2dtype' );

// Get a list of supported array data types:
var dt = dtypes();

// For each supported data type, create an array and return its WebAssembly data type...
var v;
var i;
for ( i = 0; i < dt.length; i++ ) {
    v = array2dtype( empty( 10, dt[ i ] ) );
    console.log( '%s => %s', dt[ i ], v );
}
