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!

ndarray2localeString

Serialize an ndarray as a locale-aware string.

Installation

npm install @stdlib/ndarray-to-locale-string

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 ndarray2localeString = require( '@stdlib/ndarray-to-locale-string' );

ndarray2localeString( x[, locales[, options]] )

Serializes an ndarray as a locale-aware string.

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

var x = array( [ 1, 2, 3, 4 ], {
    'shape': [ 2, 2 ]
});
// returns <ndarray>

var str = ndarray2localeString( x );
// returns <string>

The function supports the following parameters:

• x: input ndarray.
• locales: a BCP 47 language tag or an array of such strings (optional).
• options: configuration options (optional).

Notes

• The function does not serialize data outside of the buffer region defined by the ndarray view.
• For ndarrays with more than 100 elements, the function abbreviates the data, showing only the first three and last three values.

Examples

var array = require( '@stdlib/ndarray-array' );
var ndarray2localeString = require( '@stdlib/ndarray-to-locale-string' );

// Create a 2x3 ndarray:
var x = array( [ 1234.567, 9876.543, 1111.222, 3333.444, 5555.666, 7777.888 ], {
    'shape': [ 2, 3 ],
    'dtype': 'generic'
});

// Serialize using the default locale:
var str = ndarray2localeString( x );
// e.g., returns 'ndarray( \'generic\', [ 1,234.567, 9,876.543, 1,111.222, 3,333.444, 5,555.666, 7,777.888 ], [ 2, 3 ], [ 3, 1 ], 0, \'row-major\' )'

// Serialize using the English (US) locale:
str = ndarray2localeString( x, 'en-US' );
// returns 'ndarray( \'generic\', [ 1,234.567, 9,876.543, 1,111.222, 3,333.444, 5,555.666, 7,777.888 ], [ 2, 3 ], [ 3, 1 ], 0, \'row-major\' )'

// Serialize using the German locale:
str = ndarray2localeString( x, 'de-DE' );
// returns 'ndarray( \'generic\', [ 1.234,567, 9.876,543, 1.111,222, 3.333,444, 5.555,666, 7.777,888 ], [ 2, 3 ], [ 3, 1 ], 0, \'row-major\' )'

// Serialize with a maximum number of fraction digits:
str = ndarray2localeString( x, 'en-US', {
    'maximumFractionDigits': 0
});
// returns 'ndarray( \'generic\', [ 1,235, 9,877, 1,111, 3,333, 5,556, 7,778 ], [ 2, 3 ], [ 3, 1 ], 0, \'row-major\' )'
