<p>Currently two programs exist, which only downloads the output instead of putting on a web page. My understanding in GO is nothing. This is all information found on the internet and nothing is helping. Making me /really/ hate this language despite its praise. PLEASE HELP. THANK YOU.

<p>I would suggest that you refrain from starting your question like this. Saying that you hate the language even though other people speak highly of it, because you know nothing about it and can't find answers on the internet, is not going to motivate people to read your wall of code and try to help. </p>
<p>That being said, could you please state your goal a little more clearly? Are you expecting to be able to hit a certain http endpoint in your program and see the results of a function printed out? Do you need to have a web form to accept input? Do you need to accept any input?</p></pre>itsmontoya: <pre><p>You're trying to run before you can walk. Why not baby steps?</p></pre>ModerateBrainUsage: <pre><p>What's the goal of this program? There's probably a lot better way to do things than what you wrote now. I didn't check your program, since you don't say what your goals are, only that you hate it.</p>
<p>To make a string out of a float use fmt.Sprintf("%2.5f", blah) or use fmt.Fprintf() to write to a io.Writer. Why float32 instead of float64? Are you using 32bit hardware? The math package works on float64.</p>
<p>One last thing, you can replace a lot of fmt.Print() and fmt.Println() with fmt.Printf(). You can replace a lot of it with text/template too.</p>
<p>As others have said, learn to walk first and then run. It doesn't look like you have even done the Go tour. This is on the 2nd page of it:
