Alternative FP explorer:

- double precision: http://bartaz.github.io/ieee754-visualization/

- single precision: https://nebgnahz.github.io/ieee754-visualization/

This one is actually much nicer.

Mostly seems to be "TODO". It would be nice if it showed the binary representation and a number line in a graphical format. How dense are the numbers around this one? What is the next larger/smaller representable number? Is the number denormalized? etc.

Isn't that what the "epsilon" field tells us?

For a second, I thought that http://www.exploringbinary.com/converters-and-calculators/ had changed domain names.

(The rest of that site has plenty of good, extremely detailed articles about floating-point maths too.)

Thank you so very much for your link!

Simultaneously with my definite elucidation, I felt a really timely reminder that I haven't read the whole internet, and it's a beautiful thing to be informed of such a rich and established resource, just when you are getting sure that soon your bitterness and cynicism over the demise of the internet will soon inevitably pass.

Thank you, in other words, for a very useful link to what looks like it's great reading, and the whole breath of fresh air surrounding your contribution. I gush, but the aversion of creeping cynicism is genuinely something that I'm grateful for any day without exception!

I'm missing a rounding mode.
