 Function for **BgcVector2FP32**:
 
 ```c
-    inline void bgc_vector2_set_values_fp64(const double x1, const double x2, BgcVector2FP64* to);
+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:
 
 ```c
-    vector->x1 = x1;
-    vector->x2 = x2;
+to->x1 = x1;
+to->x2 = x2;
 ```
 
-You should not pass invalid pointers to these functions. The value NULL (0) is also considered invalid.
+Invalid pointers should not be passed in the **to** parameter. The NULL (0) value is also considered invalid.
 
 Example of use:
