@stdlib/array-convert

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!

convert

Convert an array to an array of a different data type.

Installation

npm install @stdlib/array-convert

Usage

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

convert( arr, dtype )

Converts an array to an array of a different data type.

var arr = [ 1.0, 2.0, 3.0 ];
var out = convert( arr, 'float32' );
// returns <Float32Array>[ 1.0, 2.0, 3.0 ]

The function supports 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.
• 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.

Examples

var discreteUniform = require( '@stdlib/random-base-discrete-uniform' ).factory;
var filledarrayBy = require( '@stdlib/array-filled-by' );
var dtypes = require( '@stdlib/array-dtypes' );
var convert = require( '@stdlib/array-convert' );

// Create a generic array:
var arr = filledarrayBy( 5, 'generic', discreteUniform( -100, 100 ) );

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

// Convert the generic array to each array data type:
var out;
var i;
for ( i = 0; i < DTYPES.length; i++ ) {
    out = convert( arr, DTYPES[ i ] );
    console.log( out );
}
