function fill( dtype, len, value ) {
    var ctor;
    var arr;
    var i;
    if ( len > MAX_TYPED_ARRAY_LENGTH ) {
        throw new RangeError( 'invalid argument. The maximum length for a typed array is '+MAX_TYPED_ARRAY_LENGTH+'.' );
    }
    ctor = ctors( dtype );
    arr = new ctor( len );
    for ( i = 0; i < len; i++ ) {
        arr[ i ] = value;
    }
    return arr;
