Setting the coordinates of a two-dimensional vector

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 BgcVector2FP32:

inline void bgc_vector2_set_values_fp32(const float x1, const float x2, BgcVector2FP32* to);

Function for BgcVector2FP32:

inline void bgc_vector2_set_values_fp64(const double x1, const double x2, BgcVector2FP64* to);

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

to->x1 = x1;
to->x2 = x2;

Invalid pointers should not be passed in the to parameter. The NULL (0) value is also considered invalid.

Example of use:

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

int main()
{
    BgcVector2FP32 my_vector;

    bgc_vector2_set_values_fp32(-2, 7, &my_vector);

    printf("x1 = %f, x2 = %f\n", my_vector.x1, my_vector.x2);

    return 0;
}
