Same Kind Casts
Return a list of array data types to which a provided array data type can be safely cast or cast within the same "kind".
Usage
var sameKindCasts = require( '@stdlib/array/same-kind-casts' );
sameKindCasts( [dtype] )
If provided a dtype
argument, returns a list of array data types to which a provided array data type can be safely cast or cast within the same "kind" (e.g., between signed integers or between floating-point numbers).
var out = sameKindCasts( 'float64' );
// e.g., returns [ 'float64', 'float32', 'generic' ]
If not provided a dtype
argument, the function returns a casting table.
var out = sameKindCasts();
// returns {...}
var f64 = out[ 'float64' ];
// returns {...}
var v = f64[ 'float32' ];
// returns 1
If provided an unrecognized or unsupported dtype
, the function returns null
.
var out = sameKindCasts( 'foo' );
// returns null
Examples
var dtypes = require( '@stdlib/array/dtypes' );
var sameKindCasts = require( '@stdlib/array/same-kind-casts' );
var DTYPES;
var list;
var i;
// Get the list of supported array data types:
DTYPES = dtypes();
// Print the list of array data types to which a data type can be cast...
for ( i = 0; i < DTYPES.length; i++ ) {
list = sameKindCasts( DTYPES[ i ] );
console.log( '%s: %s', DTYPES[ i ], list.join( ', ' ) );
