# Setting the coordinates of a two-dimensional vector

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

You can set the coordinates of vectors either directly or using functions.
The functions for setting coordinate values allow you to do this in one line.

Function for **BGC_FP32_Vector2**:

```c
inline void bgc_fp32_vector2_set_values(BGC_FP32_Vector2* const destination, const float x, const float y);
```

Function for **BGC_FP64_Vector2**:

```c
inline void bgc_fp64_vector2_set_values(BGC_FP64_Vector2* const destination, const double x, const double y);
```

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

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

Valid pointers should pass in the **destination** parameter.
The NULL (0) value is considered invalid.

This function is good for setting up the initial values of coordinates with
one-line especially when the values are fixed constants like in the example
below.

Example of use:

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

int main()
{
    BGC_FP32_Vector2 my_vector;

    bgc_fp32_vector2_set_values(&my_vector, -2.2f, 7.1f);

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

    return 0;
}
```
