nextDataType

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

Usage

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

nextDataType( [dtype] )

If provided a dtype argument, returns the next larger array 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( 'complex128' );
// 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/array/dtypes' );
var nextDataType = require( '@stdlib/array/next-dtype' );

var DTYPES;
var dt;
var i;

// Get the list of supported array 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 );
}
