# Example FltVector copy 006

#### Description

This example shows how a Vector may be modified destructively or non-destructively using the the copy and setq function.

#### Details

The original Vector.

 (define x #(float| 5.456699848175 3.141592025757 )) Returns: #

The copied Vector using the copy function.

 (setq z (copy x)) Returns: #

The copied Vector using the setq function.

 (setq twin x) Returns: #

The container named z is a copy of x (both are Vectors) and z has a separate memory space. However, the containers named x and twin point to the same memory spaces on the heap. Therefore

 (setq twin[1] 4.1234 ) Returns: #

The setq command results in the contents of both twin and x being both the same.

 twin[1] Returns: 4.1234
 x[1] Returns: 4.1234

Since z points to a different memory space, it still retained the original value which was copied from x before the values of x were modified.

 z[1] Returns: 3.141592025757

Notes and Hints

Using the setq function results in objects having the same object id. But the object that is being assigned the copied object has a different object id than original object. In this example twin and x have the same object id while z has a different object id.
