I’ve been looking at a lot of AVM2 bytecode recently with the excellent Nemo440 AIR app. Some of the code was using my inline Math.ceil() function and I noticed that the int() cast is implemented like any other function call. Today’s article will show you how to optimize the inline Math.ceil() call even further by avoiding this function call.

Inlining Math Functions

As a followup to my article on Inlining Math.ceil(), I decided to inline some more functions in the Math class. Read on for the code as well as tests proving correctness and speed.
Inline Math.ceil()
Oct 5
Math.ceil() is a common, mundane function that you likely call all the time. I know I do. If performance gets to be important and you have a Math.ceil() in some inner loop or frequently called function, consider inlining it. Below I’ll show you how and provide a test app showing you just how much CPU time you’ll save.
