Weekend project: What Every Programmer Should Know About FP Arithmetic

Am I the only one who thought "What the hell is 'Functional Programming Arithmetic' " after reading this headline? :)

I once had a more detailled look at floating-point numbers, and yes, it's quite a big topic. I like the site, because it's kept quite short, and it describes a few important aspects in regard to the usage of floating-point numbers in your programs (e.g. Comparison).

Maybe you want to mention that there's also an IEEE Standard for Floating-Point Arithmetic: http://grouper.ieee.org/groups/754/

Coincidentally, I was in the process of doing the same thing. Then I came across http://www.drdobbs.com/cpp/184403224 which said what I wanted to say, exactly.

Author of the site here.

The headline needed to be shortened to fit the 80 character limit :)

I've linked to the Wikipedia page of the IEEE standard, but adding the original source is probably a good idea.

I was saved by noting the domain after the headline.

Partly off topic:

Is it normal that I have only two real fears, Mosquitos and Floating Point Arithmetic?

(And I know most of FPA stuff and few most useful numerically stable algorithms)

BONUS POINTS: Which part of question is off-topic? :)

You seem to be missing the use of an absolute value function on your 'comparison' page.

Also, on the Binary Fractions page, in the last cell of the first table, the last term is "1x0," which should be "1x1."

Nice, informative site though.

Thanks - will fix that tonight.

Ouch. Yes, that will be fixed.
