# Two-dimensional vectors

There are two types of 2D vectors in the library:
- **BgcVector2FP32** - vector using single-precision floating-point numbers
- **BgcVector2FP64** - vector using double-precision floating-point numbers

Structure definitions:

```c
    typedef struct
    {
        float x1, x2;
    } BgcVector2FP32;

    typedef struct
    {
        double x1, x2;
    } BgcVector2FP64;
```
