@stdlib/ndarray-dtypes

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!

Data Types

List of ndarray data types.

Installation

npm install @stdlib/ndarray-dtypes

Usage

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

dtypes( [kind] )

Returns a list of ndarray data types.

var out = dtypes();
// e.g., returns [ 'binary', 'complex64', 'complex128', ... ]

When not provided a data type "kind", the function returns an array containing the following data types:

• binary: binary.
• complex64: single-precision complex floating-point numbers.
• complex128: double-precision complex floating-point numbers.
• float32: single-precision floating-point numbers.
• float64: double-precision floating-point numbers.
• generic: values of any type.
• int16: signed 16-bit integers.
• int32: signed 32-bit integers.
• int8: signed 8-bit integers.
• uint16: unsigned 16-bit integers.
• uint32: unsigned 32-bit integers.
• uint8: unsigned 8-bit integers.
• uint8c: unsigned clamped 8-bit integers.

To return the subset of data types belonging to a specified data type kind, provide a kind argument.

var out = dtypes( 'floating_point' );
// returns [...]

The function supports the following data type kinds:

• floating_point: floating-point data types.
• real_floating_point: real-valued floating-point data types.
• complex_floating_point: complex-valued floating-point data types.
• integer: integer data types.
• signed_integer: signed integer data types.
• unsigned_integer: unsigned integer data types.
• real: real-valued data types.
• numeric: numeric data types.
• typed: typed data types.
• all: all data types.

Examples

var indexOf = require( '@stdlib/utils-index-of' );
var dtypes = require( '@stdlib/ndarray-dtypes' );

var DTYPES = dtypes();

function isdtype( str ) {
    if ( indexOf( DTYPES, str ) === -1 ) {
        return false;
    }
    return true;
}

var bool = isdtype( 'float64' );
// returns true

bool = isdtype( 'int16' );
// returns true

bool = isdtype( 'uint8' );
// returns true

bool = isdtype( 'beep' );
// returns false
