    Same Kind Casts

    NPM version Build Status Coverage Status dependencies

    Return a list of ndarray data types to which a provided ndarray data type can be safely cast or cast within the same "kind".

    Installation

    npm install @stdlib/ndarray-same-kind-casts

    Usage

    var sameKindCasts = require( '@stdlib/ndarray-same-kind-casts' );

    sameKindCasts( [dtype] )

    If provided a dtype argument, returns a list of ndarray data types to which a provided ndarray 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', ... ]

    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/ndarray-dtypes' );
    var sameKindCasts = require( '@stdlib/ndarray-same-kind-casts' );
    
    var DTYPES;
    var list;
    var i;
    
    // Get the list of supported ndarray data types:
    DTYPES = dtypes();
    
    // Print the list of ndarray 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( ', ' ) );
    }
