Code updated for 5.20+
i was asked how to set a positive value to a negative and backward... here is my small idea...
Code: Select all
Procedure InvertValue(val)
ProcedureReturn val - (val+val)
EndProcedure
Debug InvertValue(24) ; returns -24
Debug InvertValue(-318) ; returns 318

It works well but it is just 5 or 6 times slower than a = -a

Va!n,
Sorry; With all my respects; i think these kind of tricks are too simple.
I'd add 'Beginners' word before the title of the thread, or a way to say the skill degree of the trick (tip) or something.
Just only my opinion

If you want to write really obfuscated code you can use this:

Psychopanta, you are forgetting an important point. Adding the word "beginner" to the post means one more word for the browser to process and that eats up valuable CPU time!

@netmaestro,
You mean that laziness means better CPU performances ?
I should beat 128bits CPUs planned for the next decade ...

I ever thought that clever people are lazy.
Just because lower eneergy comsuption means higher skills ...
Maybe you will notice that the shortest a philosophical sentence is, the largest signification it may have. It may, just ... pay if you want to know more. I am lazy, but if you pay I will explain you more.

Yes.
But that doesn't mean that lazy people are clever

Code: Select all
result.l = val - (val+val)
result.l = val - val - val
result.l = 0 - val
result.l = -val
