Hello, don't scold me too much please, I'm just learning the language and OOP in general.
Can you tell me why when I try to multiply the entire formula assigned to ExtATRBuffer[i]=.... When I multiply by 1 it shows the actual value on the chart, when I multiply by fractional 0.5 n.e. some values are up and down from the zero line
What should I do to avoid error?
the final bill needs actual ATP value multiplied by a constant that can be changed...
thanks to all who replied!!!

Try to open a file that doesn't exist using FileOpen()...
I've read about this. The only clue may lie in this phrase"The name of the file to be opened, may contain sub-folders. If the file is opened for writing, the specified subfolders will be created if there are none. "But even here it says some subfolders, maybe it's a reference to the fact that in this directory in these subfolders the file will be created, because it's not written normally. You can write normally, if there is no file it will be created. It's not like I'm a scientist to guess all the details. I still don't even understand how many functions work, because there is no function code or a proper description. You know, they throw you a certain bone, and you understand for yourself whether it's edible or not.

How do you meet the sun in the morning? Have you studied all astronomy?
Standard functions aren't for figuring out their inner workings. They're for using them. And the description is in the documentation.
I told you to use FileOpen() to create a new file. But no..., you have to make a ten-page chorus instead of just "take it and use it". Well, sometimes you can say "thank you" to those who help.
Hello.
Isn't anyone going to say anything about the Bilder post?
Maybe it makes sense to put it in a new thread, so that more people will see it? If so, please ask the moderators to post it... Or create one yourself?
