# Copying of coordinate values

[Русская версия / Russian version](copy-rus.md)

The function for **BGC_FP32_Vector2**:

```c
inline void bgc_fp32_vector2_copy(BGC_FP32_Vector2* const destination, const BGC_FP32_Vector2* const source);
```

The function for **BGC_FP64_Vector2**:

```c
inline void bgc_fp64_vector2_copy(BGC_FP64_Vector2* const destination, const BGC_FP64_Vector2* const source);
```

These functions allow to copy the values of the coordinates of one 2D-vector to another 2D-vector of the same type.

Each of these functions is equivalent to the following lines of code:

```c
destination->x = source->x;
destination->y = source->y;
```

### Parameters

|  Parameter  | Direction  | Description                                                             |
| ----------- | ---------- | ----------------------------------------------------------------------- |
| destination |     out    | A pointer to a vector to set coordinate values from *source*            |
|   source    |     in     | A pointer to a vector which coordinates will be copied to *destination* |

The **source** and **destination** parameters must be valid pointers. The NULL (0) value is also considered invalid.

### Example

```c
#include <stdio.h>
#include <basic-geometry.h>

int main()
{
    BGC_FP32_Vector2 v1, v2;

    v1.x = -2.0f;
    v1.y = 7.4f;

    bgc_fp32_vector2_copy(&v2, &v1);

    printf("x = %f, y = %f\n", v2.x, v2.y);

    return 0;
}
```
