dtypeAlignment

Return the alignment (in bytes) for an underlying array data type.

Installation

npm install @stdlib/ndarray-base-dtype-alignment

Usage

var dtypeAlignment = require( '@stdlib/ndarray-base-dtype-alignment' );

dtypeAlignment( [dtype] )

Returns the alignment (in bytes) for an underlying array data type.

var out = dtypeAlignment( 'float64' );
// returns 8

out = dtypeAlignment( 'generic' );
// returns null

If provided an unknown or unsupported data type, the function returns null.

var out = dtypeAlignment( 'foobar' );
// returns null

If not provided a data type value, the function returns an object mapping data type strings to alignments (in bytes).

var obj = dtypeAlignment();
// returns {...}

Examples

var logEachMap = require( '@stdlib/console-log-each-map' );
var dtypeAlignment = require( '@stdlib/ndarray-base-dtype-alignment' );

var dtypes = [
    'float64',
    'float32',
    'int8',
    'uint8',
    'uint8c',
    'int16',
    'uint16',
    'int32',
    'uint32',
    'binary',
    'generic',
    'foobar'
];

logEachMap( '%s => %s', dtypes, dtypeAlignment );
