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!

List of output ndarray data type policies.

## Installation ```bash npm install @stdlib/ndarray-output-dtype-policies ``` Alternatively, - To load the package in a website via a `script` tag without installation and bundlers, use the [ES Module][es-module] available on the [`esm`][esm-url] branch (see [README][esm-readme]). - If you are using Deno, visit the [`deno`][deno-url] branch (see [README][deno-readme] for usage intructions). - For use in Observable, or in browser/node environments, use the [Universal Module Definition (UMD)][umd] build available on the [`umd`][umd-url] branch (see [README][umd-readme]). The [branches.md][branches-url] 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.
## Usage ```javascript var policies = require( '@stdlib/ndarray-output-dtype-policies' ); ``` #### policies() Returns a list of ndarray data type policies. ```javascript var out = policies(); // e.g., returns [ 'same', 'promoted', ... ] ``` The output array contains the following data type policies: - `same`: return the same data type. - `promoted`: return a promoted data type. - `accumulation`: return a data type amenable to accumulation. - `boolean`: return a boolean data type. - `boolean_and_generic`: return a boolean or "generic" data type. - `signed_integer`: return a signed integer data type. - `signed_integer_and_generic`: return a signed integer or "generic" data type. - `unsigned_integer`: return an unsigned integer data type. - `unsigned_integer_and_generic`: return an unsigned integer or "generic" data type. - `integer`: return an integer data type (i.e., either signed or unsigned). - `integer_and_generic`: return an integer (i.e., either signed or unsigned) or "generic" data type. - `floating_point`: return a floating-point data type (i.e., either real-valued or complex-valued). - `floating_point_and_generic`: return a floating-point (i.e., either real-valued or complex-valued) or "generic" data type. - `real_floating_point`: return a real-valued floating-point data type. - `real_floating_point_and_generic`: return a real-valued or "generic" floating-point data type. - `complex_floating_point`: return a complex-valued floating-point data type. - `complex_floating_point_and_generic`: return a complex-valued or "generic" floating-point data type. - `real`: return a real-valued data type. - `real_and_generic`: return a real-valued or "generic" data type. - `numeric`: return a numeric data type. - `numeric_and_generic`: return a numeric or "generic" data type. - `integer_index`: return an integer index data type. - `integer_index_and_generic`: return an integer index or "generic" data type. - `boolean_index`: return a boolean index data type. - `boolean_index_and_generic`: return a boolean index or "generic" data type. - `mask_index`: return a mask index data type. - `mask_index_and_generic`: return a mask index or "generic" data type. - `default`: return the default data type. - `default_index`: return the default index data type.
## Examples ```javascript var indexOf = require( '@stdlib/utils-index-of' ); var policies = require( '@stdlib/ndarray-output-dtype-policies' ); var POLICIES = policies(); function isPolicy( str ) { if ( indexOf( POLICIES, str ) === -1 ) { return false; } return true; } var bool = isPolicy( 'same' ); // returns true bool = isPolicy( 'real_floating_point' ); // returns true bool = isPolicy( 'promoted' ); // returns true bool = isPolicy( 'beep' ); // returns false ```
