Built-in functions in pl / sql?

I have 5 lines of code as a function that is called 100,000 times, there is a way to make the function inline so that I do not experience the overhead in PL / SQL. Oracle 9i is the version I'm using.

Update: Styling the code doesn't have much improvement, but I got 2 seconds. Now I am looking for an efficient version of the float data type in pl / sql. BINARY FLOAT is not working, NUMBER (10.5) is the one that is already in use.

You have determined that the function call overhead does not contribute much to the performance problem, so in this case, the attachment will not be useful.
