Casting Modes
List of ndarray casting modes.
Installation
npm install @stdlib/ndarray-casting-modes
Usage
var modes = require( '@stdlib/ndarray-casting-modes' );
modes()
Returns a list of ndarray casting modes.
var out = modes();
// returns [ 'none', 'equiv', 'safe', 'mostly-safe', 'same-kind', 'unsafe' ]
The output array
contains the following modes:
none
: only allow casting between identical types.equiv
: allow casting between identical and byte swapped types.safe
: only allow "safe" casts.mostly-safe
: allow "safe" casts and, for floating-point data types, downcasts.same-kind
: allow "safe" casts and casts within the same kind (e.g., between signed integers or between floats).unsafe
: allow casting between all types (including between integers and floats).
Examples
var indexOf = require( '@stdlib/utils-index-of' );
var modes = require( '@stdlib/ndarray-casting-modes' );
var MODES = modes();
var bool;
function isMode( str ) {
if ( indexOf( MODES, str ) === -1 ) {
return false;
}
return true;
}
bool = isMode( 'none' );
// returns true
bool = isMode( 'equiv' );
// returns true
bool = isMode( 'safe' );
// returns true
bool = isMode( 'mostly-safe' );
// returns true
bool = isMode( 'same-kind' );
// returns true
bool = isMode( 'unsafe' );
// returns true
bool = isMode( 'beep' );
// returns false
