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!
Return a list of array data types to which a provided array data type can be safely cast or cast within the same "kind".
npm install @stdlib/array-same-kind-castsAlternatively,
- To load the package in a website via a
scripttag without installation and bundlers, use the ES Module available on theesmbranch (see README). - If you are using Deno, visit the
denobranch (see README for usage intructions). - For use in Observable, or in browser/node environments, use the Universal Module Definition (UMD) build available on the
umdbranch (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.
var sameKindCasts = require( '@stdlib/array-same-kind-casts' );If provided a dtype argument, returns a list of array data types to which a provided array data type can be safely cast or cast within the same "kind" (e.g., between signed integers or between floating-point numbers).
var out = sameKindCasts( 'float64' );
// e.g., returns [ 'float64', 'float32', 'complex64', 'complex128', 'generic' ]If not provided a dtype argument, the function returns a casting table.
var out = sameKindCasts();
// returns {...}
var f64 = out[ 'float64' ];
// returns {...}
var v = f64[ 'float32' ];
// returns 1If provided an unrecognized or unsupported dtype, the function returns null.
var out = sameKindCasts( 'foo' );
// returns nullvar dtypes = require( '@stdlib/array-dtypes' );
var sameKindCasts = require( '@stdlib/array-same-kind-casts' );
// 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 cast...
var list;
var i;
for ( i = 0; i < DTYPES.length; i++ ) {
list = sameKindCasts( DTYPES[ i ] );
console.log( '%s: %s', DTYPES[ i ], list.join( ', ' ) );
}@stdlib/array-convert: convert an array to an array of a different data type.@stdlib/array-convert-same: convert an array to the same data type as a second input array.@stdlib/array-dtypes: list of array data types.@stdlib/array-safe-casts: return a list of array data types to which a provided array data type can be safely cast.@stdlib/ndarray-same-kind-casts: return a list of ndarray data types to which a provided ndarray data type can be safely cast or cast within the same kind.
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.
