Stack Overflow is not an appropriate forum for broad architectural questions like this. You may find the Software Engineering or Code Review sites on the Stack Exchange network more accommodating. That said, a method should only need parameters passed that it needs for its work. If you are finding yourself passing a lot of parameters on a regular basis, your design is flawed. There are countless alternatives to the approach you describe above, many of which much more in keeping with general OOP principles, and which lead to easier-to-write, easier-to-maintain code. — Peter Duniho 32 secs ago
I'd delete for now and try testing any improved solution with large and wee double and many other values. Maybe post on Code Review. I think you would learn a lot. — chux - Reinstate Monica 52 secs ago

Please go through the intro tour, the help center and how to ask a good question to see how this site works and to help you improve your current and future questions, which can help you get better answers. You need to identify where your code is running slowly, show your attempts to improve it, and focus on what still isn't working for you. As given, this might be a candidate for Code Review, but not here. — Prune 58 secs ago

@Peilonrayz I've downvoted that question years ago. It was a stupid idea then, it has proven to be a stupid idea today.
 
@Mast "it has proven to be a stupid idea today", do you have a source? Last I heard there was an increase in quality. Not really sure how else you could fix the problem, have like a "do you know the rules" test before asking a question
 
@Peilonrayz A quiz would be nice, like a captcha.
Source is personal experience, YMMV.
 
@Mast I'm sure convincing SE of the benefits of our long form captcha would be a journey ;)
 
Definitely.
