   - fuction that multiplies fa and fb and divides it by 2^32 is fatest.
   - from the above result, it can be seen that there is a difference in call speed depending on how the shift operation is used.

+- c. summary
+  - It can be seen that the speed of each function appears differently depending on the number calculated or other situations.
+  - If making good use of the shift operation, can create a function that is optimized for each situation.
