And lots of posts to AH about floating-point arithmetic.

Hey... wait a minute...

I had to look up "floating-point arithmetic," and now that I've read the definition, I still don't understand it.

It's frustrating to know that people are turned on by things I don't even understand.

Non whole numbers, ie: decimal numbers.

Computers can do integer math easily, it's very basic stuff. Floating point is significantly more complicated for computers to do, and early PC computers had a dedicated chip just for floating point operations. Now, the GPU does a lot of floating point calculations (for graphics and AI), even though all CPUs have a floating point unit built-in.

Ooh! That’s so erotic.

How do I give a red H to a thread post?

TLDR: there are infinitely many numbers in mathematics, but most of them can't be represented precisely in computer arithmetic. Floating-point is about how one approximates the former with the latter.

On some calculator models, if you divide 1 by 3 and then multiply the result by 3, instead of getting back to 1, you'll end up with something like 0.999999. That's a "floating-point error" caused by inability to represent 1/3 exactly.

(There are some specialised methods that can represent 1/3 exactly, but they're not suitable for general use and they still fail for other numbers.)

I choose to celebrate the diverse and frequently bizarre tapestry of human enthusiasm. Sometimes with a raised eyebrow.

Also very large whole numbers sometimes. Friends don't let friends store credit card numbers as floats or doubles...
 
"There are more things in heaven and earth, Horatio, / Than are dreamt of in your philosophy"

The working title of one of my stories was "Those things undreamt of":
Even I was unsettled here -- I, who had on multiple occasions faced stabbing spears, flying bullets and slashing blades, who in India had once or twice encountered things that surely were undreamt of in Horatio's philosophy, so to speak.
But in the end I decided that it probably wouldn't attract readers, so I called it "The Countesses of Tannensdal". Given the viewing numbers, I might have chosen poorly.
