Package Exports

@stdlib/ndarray-casting-modes
@stdlib/ndarray-casting-modes/lib/index.js

This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (@stdlib/ndarray-casting-modes) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

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!

Casting Modes

List of ndarray casting modes.

Installation

npm install @stdlib/ndarray-casting-modes

Usage

var modes = require( '@stdlib/ndarray-casting-modes' );

modes()

Returns a list of ndarray casting modes.

var out = modes();
// returns [ 'none', 'equiv', 'safe', 'mostly-safe', 'same-kind', 'unsafe' ]

The output array contains the following modes:

none: only allow casting between identical types.
equiv: allow casting between identical and byte swapped types.
safe: only allow "safe" casts.
mostly-safe: allow "safe" casts and, for floating-point data types, downcasts.
same-kind: allow "safe" casts and casts within the same kind (e.g., between signed integers or between floats).
unsafe: allow casting between all types (including between integers and floats).

Examples

var indexOf = require( '@stdlib/utils-index-of' );
var modes = require( '@stdlib/ndarray-casting-modes' );

var MODES = modes();
var bool;

function isMode( str ) {
    if ( indexOf( MODES, str ) === -1 ) {
        return false;
    }
    return true;
}

bool = isMode( 'none' );
// returns true

bool = isMode( 'equiv' );
// returns true

bool = isMode( 'safe' );
// returns true

bool = isMode( 'mostly-safe' );
// returns true

bool = isMode( 'same-kind' );
// returns true

bool = isMode( 'unsafe' );
// returns true

bool = isMode( 'beep' );
// returns false

Notice

This package is part of stdlib, a standard library for JavaScript and Node.js, with an emphasis on numerical and scientific computing. The library provides a collection of robust, high performance libraries for mathematics, statistics, streams, utilities, and more.
