+# Functions that set the values of the versor components
+
+Special functions are provided to specify specific values ??for the versor components.
+
+For the **BgFP32Versor** type, the function has the form:
+
+```c
+    inline void bgc_versor_set_values_fp32(const float s0, const float x1, const float x2, const float x3, BgcVersorFP32* versor);
+```
+
+For the **BgFP64Versor** type, the function has the form:
+
+```c
+    inline void bgc_versor_set_values_fp64(const double s0, const double x1, const double x2, const double x3, BgcVersorFP64* versor);
+```
+
+These functions set the values ??passed in the **s0**, **x1**, **x2**, and **x3** parameters to the corresponding components of the versor passed by pointer in the **versor** parameter. But if the resulting state is not a normalized quaternion, then the functions normalize the versor.
+
+The **versor** parameter must be a valid pointer and must not be NULL.
+
+These functions are also well suited for initializing the state of variables of types **BgFP32Versor** and **BgFP64Versor**, as are the functions [bgc_versor_reset_fp32 and bgc_versor_reset_fp64](./versor-reset-eng.md).
+
+```c
+    #include <stdio.h>
+    #include <basic-geometry.h>
+    
+    int main() {
+        BgcVersorFP64 versor;
+        
+        bgc_versor_set_values_fp64(1, 2, 3, 4, &versor);
+        
+        printf("Versor: (%lf, %lf, %lf, %lf)\n", versor.s0, versor.x1, versor.x2, versor.x3);
+        
+        return 0;
+    }
+```
+
+Result:
+
+```
+    Versor: (0.182574, 0.365148, 0.547723, 0.730297)
+```
+
+If zeros are passed to the function as component values, then the versor, the pointer to which is passed in the **versor** parameter, will be set to the state corresponding to the absence of rotation:
+
+```c
+    bgc_versor_set_values_fp64(0, 0, 0, 0, &versor);
+```
+
+Result:
+
+```
+    Versor: (1.000000, 0.000000, 0.000000, 0.000000)
+```
