It is worth noting that in some cases you are doing want non-configurable "really hard-coded" figures in your code. There are a selection of well known types which includes 0x5F3759DF which is Employed in the optimized inverse sq. root algorithm.
Past variations stored the "code" inside a database desk. The final version, UniPaas shops the code in xml documents. I could send out you an case in point, if PachinSV would not answer you prior to. Even so the documents are quite massive: the smallest xml file I've in a very take a look at application is 4000 bytes, and any software is crafted from not less than eleven documents, an vacant software is 7600 bytes.
My stage however was to spotlight that in terms of magic numbers, the maintainability from the code is A significant challenge, significantly when if you don't comprehend it's function you would possibly improve or use a magic range, with unintended side effects Consequently.
In the gnuwin32 offer I have uncovered magic and magic.mgc. I put them to the same folder, and received WindowsError: [Error 126] on libmagic = None # Let's attempt to discover magic or magic1 dll = ctypes.
My code is filled with world-wide constants like HzPerMHz and msecPerSecond. These will never alter, but they make the meaning clearer, and supply some defense in opposition to typos.
Whether each given implementation in fact utilizes any "magic" is a special query (you will find portions of STL in which "magic" would assist, but not absolutely required).
The end result is ALL primary values are changed with symbolic constants. As I concur with all your conclusion I obtain Krol this a lot less than excellent.
When you feel that this query is usually enhanced And perhaps reopened, take a look at the assistance Middle for steerage. Shut 12 years back.
Magic figures are any selection within your code that won't instantly evident to someone with little or no know-how.
For example, you might have a magic quantity of 0x12345678. If you see that magic variety, it is a truthful guess you might be looking at a file of the proper structure. If the thing is, on the other hand, 0x78563412, it is a fair guess that you're seeing an endian-swapped version of the same file structure.

Our monster object provides a attribute termed life_force, that is an integer. The quantities have meanings that are not knowable or very clear without words and phrases to provide meaning. Consequently, we commence by arbitrarily saying:
