# Swapping
The exchange functions allow two vectors of the same type to exchange coordinate values.

The exchange functions allow two vectors of the same type to exchange coordinate
values.
Function for **BGC_FP32_Vector2**:
```c
inline void bgc_vector2_swap_fp32(BgcVector2FP32* vector1, BgcVector2FP32* vector2);
inline void bgc_fp32_vector2_swap(BGC_FP32_Vector2* const vector1, BGC_FP32_Vector2* const vector2);

Function for **BGC_FP64_Vector2**:
```c
inline void bgc_vector2_swap_fp64(BgcVector2FP64* vector1, BgcVector2FP64* vector2);
inline void bgc_fp64_vector2_swap(BGC_FP64_Vector2* const vector1, BGC_FP64_Vector2* const vector2);
```
The **vector1** and **vector2** parameters must not be invalid pointers. The NULL (0) value is also considered invalid.
The **vector1** and **vector2** parameters must be valid pointers.
The NULL (0) value is considered invalid.
Vector **vector1** after calling this function will have the coordinate values that vector **vector2** had before calling the function.
Vector **vector1** after calling this function will have the coordinate values
that vector **vector2** had before calling the function.
And vector **vector2** after calling this function will have the same coordinate values that vector **vector1** had before calling the function.
