Package Exports

@stdlib/ndarray-next-dtype

This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (@stdlib/ndarray-next-dtype) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

Readme

Next Data Type

Return the next larger ndarray data type of the same kind.

Installation

npm install @stdlib/ndarray-next-dtype

Usage

var nextDataType = require( '@stdlib/ndarray-next-dtype' );

nextDataType( [dtype] )

If provided a dtype argument, returns the next larger ndarray data type of the same kind.

var out = nextDataType( 'float32' );
// returns 'float64'

If a data type does not have a next larger data type or the next larger data type is not supported, the function returns -1.

var out = nextDataType( 'float64' );
// returns -1

If not provided a dtype argument, the function returns a table.

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

If provided an unrecognized or unsupported dtype, the function returns null.

var out = nextDataType( 'foo' );
// returns null

Examples

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

var DTYPES;
var dt;
var i;

// Get the list of supported ndarray data types:
DTYPES = dtypes();

// Print the next larger data type for each supported data type...
for ( i = 0; i < DTYPES.length; i++ ) {
    dt = nextDataType( DTYPES[ i ] );
    console.log( '%s => %s', DTYPES[ i ], dt );
}
