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!

Safe Casts

Return a list of array data types to which a provided array data type can be safely cast.

Usage

import safeCasts from 'https://cdn.jsdelivr.net/gh/stdlib-js/array-safe-casts@deno/mod.js';

safeCasts( [dtype] )

If provided a dtype argument, returns a list of array data types to which a provided array data type can be safely cast.

var out = safeCasts( 'float32' );
// e.g., returns [ 'float32', 'float64', 'complex64', 'complex128', 'generic' ]

If not provided a dtype argument, the function returns a casting table.

var out = safeCasts();
// returns {...}

var f32 = out[ 'float32' ];
// returns {...}

var v = f32[ 'float64' ];
// returns 1

If provided an unrecognized or unsupported dtype, the function returns null.

var out = safeCasts( 'foo' );
// returns null

Examples

import dtypes from 'https://cdn.jsdelivr.net/gh/stdlib-js/array-dtypes@deno/mod.js';
import safeCasts from 'https://cdn.jsdelivr.net/gh/stdlib-js/array-safe-casts@deno/mod.js';

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

// Print the list of array data types to which a data type can be safely cast...
var list;
var i;
for ( i = 0; i < DTYPES.length; i++ ) {
    list = safeCasts( DTYPES[ i ] );
    console.log( '%s: %s', DTYPES[ i ], list.join( ', ' ) );
}

Notice

This package is part of stdlib, a standard library 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.
