# Resetting the state of a 2D vector

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

These functions set all coordinates of 2D vectors to 0.

Function for **BGC_FP32_Vector2**:

```c
inline void bgc_fp32_vector2_reset(BGC_FP32_Vector2* const vector);
```

Function for **BGC_FP64_Vector2**:

```c
inline void bgc_fp64_vector2_reset(BGC_FP64_Vector2* const vector);
```

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

```c
vector->x = 0;
vector->y = 0;
```

You should pass valid pointers to these functions. The NULL (0) value is also
considered invalid.

This function is good for setting up the initial state of a 2D vector.

Example of use:

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

int main()
{
    BGC_FP32_Vector2 v;

    bgc_fp32_vector2_reset(&v);

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

    return 0;
}
```
