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!

char2dtype

Return the data type string associated with a provided single letter character abbreviation.

Installation

npm install @stdlib/ndarray-base-char2dtype

Alternatively,

• To load the package in a website via a script tag without installation and bundlers, use the ES Module available on the esm branch (see README).
• If you are using Deno, visit the deno branch (see README for usage intructions).
• For use in Observable, or in browser/node environments, use the Universal Module Definition (UMD) build available on the umd branch (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.

Usage

var char2dtype = require( '@stdlib/ndarray-base-char2dtype' );

char2dtype( [ch] )

Returns the data type string associated with a provided single letter character abbreviation.

var out = char2dtype( 'd' );
// returns 'float64'

out = char2dtype( 'i' );
// returns 'int32'

If provided an unknown or unsupported single letter character abbreviation, the function returns null.

var out = char2dtype( '(' );
// returns null

If not provided a data type string, the function returns an object mapping single letter character abbreviations to data type strings.

var out = char2dtype();
// returns {...}

Examples

var dtypeChar = require( '@stdlib/ndarray-base-dtype-char' );
var char2dtype = require( '@stdlib/ndarray-base-char2dtype' );

var chars = [
    dtypeChar( 'float64' ),
    dtypeChar( 'float32' ),
    dtypeChar( 'int8' ),
    dtypeChar( 'uint8' ),
    dtypeChar( 'uint8c' ),
    dtypeChar( 'int16' ),
    dtypeChar( 'uint16' ),
    dtypeChar( 'int32' ),
    dtypeChar( 'uint32' ),
    dtypeChar( 'binary' ),
    dtypeChar( 'generic' ),
    '('
];

var i;
for ( i = 0; i < chars.length; i++ ) {
    console.log( '%s => %s', chars[ i ], char2dtype( chars[ i ] ) );
}
