# Copying
[Русская версия / Russian version](copy-rus.md)
The copy functions allow you to copy the coordinate values of one vector to another vector.
Function for **BgcVector2FP32**:
Function for **BGC_FP32_Vector2**:
```c
inline void bgc_vector2_copy_fp32(const BgcVector2FP32* from, BgcVector2FP32* to);
inline void bgc_fp32_vector2_copy(BGC_FP32_Vector2* const destination, const BGC_FP32_Vector2* const source);
```
Function for **BgcVector2FP64**:
Function for **BGC_FP64_Vector2**:
```c
inline void bgc_vector2_copy_fp64(const BgcVector2FP64* from, BgcVector2FP64* to);
inline void bgc_fp64_vector2_copy(BGC_FP64_Vector2* const destination, const BGC_FP64_Vector2* const source);
```
Each of these functions is equivalent to the following lines of code:
```c
to->x1 = from->x1;
to->x2 = from->x2;
destination->x = source->x;
destination->y = source->y;
```
The **from** and **to** parameters must not be invalid pointers. The NULL (0) value is also considered invalid.
The **source** and **destination** parameters must be valid pointers.
The NULL (0) value is also considered invalid.
The **from** parameter must be a pointer to a two-dimensional vector whose coordinates are to be copied. The coordinates of the **from** vector will not change after the function call.
The **source** parameter must be a pointer to a two-dimensional vector whose
coordinates are to be copied. The coordinates of the **source** vector will
not change after the function call.
The **to** parameter must be a pointer to a two-dimensional vector whose coordinates are to be changed. The coordinates of the **to** vector will become the same as those of the **from** vector after the function call.
The **destination** parameter must be a pointer to a two-dimensional vector
whose coordinates are to be changed. The coordinates of the **destination**
vector will become the same as those of the **source** vector after the function
call.
