Ok. Based on your answer, you don't understand very much about computers. Maybe it makes sense that you're leaning on LLMs this early in your career. But it will bite you eventually.
Every x86 computer uses IEEE 754 floats, that's what you, the programmer, needs to be able to reason about.
You still need to understand floating point errors and catastrophic cancellation. And simple techniques to deal with that, like summing from small to big, or using Kahan sums, or limiting the range where your approximation is used. You can use a library for some of these, but then you need to know what the library is doing, and how to access these functions.
But the problem seems to be that you have a skill issue, and the LLM will only make your skill issues worse. Stop leaning on it or you'll never be able to stand on your own.
I said this situation is reminiscent of how we took computer arithmetic out of the hands of programmers in the 80s and you gave me a big lecture about how easy it was to make your own sine function which concluded in you explaining that every computer (mostly) uses IEEE floats.
No shit.
What do you think we did in the 1980s to take computer arithmetic away from working programmers? We standardized computer arithmetic so instead of needing a numerical analyst on hand you just need to read that Goldberg article you’ll run off to Google now.
You live in the land of milk and honey and you dare lecture someone about effort. You have absolutely no clue what world we left behind, but you’re happy to talk about who is and isn’t learning.
Standardization is a good thing. I never said it wasn't. You're just arguing with a strawman. Your two last posts aren't even related to the discussion at hand.
Here is what I said:
“ This shift is an analogous to how we took having to do computer arithmetic out of the hands of programmers in the 80s. There used to be a substantial part of programming that was just a computer arithmetic. Now, almost nobody does that. Nobody in this thread could build a full adder if their life depended on it or produce an accurate sin function.”
It is truly not my fault that you proceeded to lecture me for multiple posts just to reach the conclusion that I SET OUT FOR YOU: standardization of computer arithmetic is good and makes it so that someone doing math on a computer doesn’t need to become an expert on how the computer does math.
As I said when you first insinuated yourself: I don’t need your help to be an engineer or a developer, thank you. You persisted anyway and embarrassed yourself.
