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!
Resolve the data type that results from applying promotion rules to a provided list of data types.
npm install @stdlib/ndarray-base-promote-dtypesAlternatively,
- 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 promoteDataTypes = require( '@stdlib/ndarray-base-promote-dtypes' );Returns a data type that results from applying promotion rules to a provided list of data types.
var dt = promoteDataTypes( [ 'float32', 'float64' ] );
// returns 'float64'The function returns null if provided data types which cannot be safely cast to a promoted data type.
var dt = promoteDataTypes( [ 'binary', 'complex128' ] );
// returns nullvar dtypes = require( '@stdlib/ndarray-dtypes' );
var cartesianProduct = require( '@stdlib/array-base-cartesian-product' );
var logEachMap = require( '@stdlib/console-log-each-map' );
var promoteDataTypes = require( '@stdlib/ndarray-base-promote-dtypes' );
// Get the list of supported data types:
var dt = dtypes();
// Generate data type pairs:
var pairs = cartesianProduct( dt, dt );
// Resolve promoted data types:
logEachMap( '(%s) => %s', pairs, promoteDataTypes );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.
