I just tried it again, and it still isn't working. At this point I'm starting to blame my text editor. :ghost: Or a curse. :think: Make sure you're saving where you think you're saving, compiling the file(s) you think you're compiling, and running the executable you think you're running.

That should work, so if it doesn't you weren't running the right code

Then you did it wrong. Show me how you put it in.

Code: Select all

double dsigmoid(double x){
	double e=2.71828;
	double k=0;
	if (x>700){
		return 0;
	}
	double j=pow(e, x);
	double l=j+1;
	double h=pow(l,2);
	k=j/h;
	return k;
}

Here you go.

Hi

Well, actually putting the code I gave you in the function at all would probably help

I did. That was the first thing I tried. It was completely ignored by the compiler.

Then you did it wrong. What's your entire code now?

Do you really want to know?

Code: Select all
if (x>700){
    return 0;
}

I'd love to say that worked, but it didn't. Still got NaN.

Hello, I'm back, soliciting more programming advice from good, hardworking... I was going somewhere with this I swear. :silent: How do I make this function return zero when x is greater then 700? :think: double e=2.71828; double k=0; if (x<700){ double j=pow(e, x); double l=j+1; double h=pow(l,2); k...

Have you tried Stack Overflow? Yeah, I don't go there anymore. They have a tendency to tell me that I'm asking a question that has already been asked, when it clearly hasn't been asked before. :ghost: I'm trying to think whether -- from the point of view of doing this in 80x86 assembly language -- ...

Open a file with W, or RW, or A flags to write. Move the cursor to wherever you want to write to (this is why A is great, it STARTS at the end) Then write data. Then either repeat, or close the file descriptor. [solid snake]A Flag?[/solid snake] :think: A Flag is an option. In this case, 'Write' 'R...

Your tool is lower level, that's all. 'Twas a joke, playing off of the fact that assembly is the lowest I've been, with nothing in between that and C++. :ghost: Open a file with W, or RW, or A flags to write.

Re: Questions about Assembly

Tue Jun 23, 2020 5:03 pm

Linux Filesystems should be completely irrelevant to you. As these systems are the same on any OS. You open a File, get presented a File Descriptor. You then need to pass the FD to any file operation you intend to do. You also need to move the seek header on the file back and forward. As it reads o...

Re: Questions about Assembly

Tue Jun 23, 2020 6:56 am

Are the file descriptor and the file name two different things? :think: Yes. Though I know nothing about ASM. A file name is simply the human readable method of finding a specific item through the file system. A file descriptor is local reference to a file. An FD is created when you 'open' a file w...
