In the digital world, understanding numerical notations like decimal, binary, and two’s complement can provide a substantial advantage and presents opportunities for improved problem-solving. The journey starts with the basic foundation of decimal …
I did not click through the tracking link to get the rest of the article but it looks like the generic fluff ChatGPT wrote when I asked it about Exploring Binary. It’s worse than fluff actually; I don’t see how knowing numerical notations helps with problem solving.
If you’ve read anything on this site you’d know immediately that I didn’t write that. Will AI ever be able to write an article indistinguishable from one of my own? I don’t think so.
It would be interesting to know how it’s taught today (it’s been a very long time since I was taught it). I can’t imagine though that the person teaching it wouldn’t say — within a sentence or two of saying “floating-point” — that it “can’t represent all decimal numbers accurately”.
That prompted me to look through my box of thirty plus year old college (undergraduate) notebooks. I found notebooks for four classes in which I was taught floating-point. The notes from three of those classes confirm what I thought — that we were warned early of the decimal/binary mismatch. But in the first class of the four — the beginner’s class — it’s less clear what we were told. I’ll show you images of the relevant excerpts from my notes. (I notice I had some elements of cursive in my handwriting back then.)
Google Reader is going away tomorrow, July 1, 2013. That means the majority of my RSS subscribers will have to find another RSS reader. I wish I could recommend one, but I am still trying to find a comparable replacement myself.
Since I am new to blogging (I just started this blog a month ago), my internet goals for 2009 are my goals for Exploring Binary specifically. I’d like to get this blog off the ground before I try anything else!
I’ve been maintaining a long list of things I want to accomplish with this blog, but I whittled it down to the most important goals — all challenging but realistically attainable:
