isSameKindCast

Determine whether an ndarray data type can be safely cast to, or is of the same "kind" as, another ndarray data type.

Usage

var isSameKindCast = require( '@stdlib/ndarray/base/assert/is-same-kind-data-type-cast' );

isSameKindCast( from, to )

Returns a boolean indicating whether an ndarray data type can be safely cast to, or is of the same "kind" as, another ndarray data type (e.g., casting between signed integers or between floats).

var bool = isSameKindCast( 'float32', 'float64' );
// returns true

bool = isSameKindCast( 'uint16', 'int16' );
// returns false

Examples

var cartesianSquare = require( '@stdlib/array/cartesian-square' );
var dtypes = require( '@stdlib/ndarray/dtypes' );
var isSameKindCast = require( '@stdlib/ndarray/base/assert/is-same-kind-data-type-cast' );

// Generate a list of dtype pairs:
var dt = cartesianSquare( dtypes() );

// For each data type pair, determine whether one can cast from one data type to another...
var i;
for ( i = 0; i < dt.length; i++ ) {
    console.log( '%s. Allowed cast? %s.', dt[i].join( ' => ' ), isSameKindCast.apply( null, dt[i] ) );
}
