merge request: Single and Double

If you want to have Single and Double in one page, then why not have a "Floating point" (or similar name) page? --Bart (talk) 17:30, 28 March 2018 (CEST)

I did not create Single and Double, Djzepi did. I saw it and noticed very similar content, so I de-duplicated it. I'm pro merge, yes, definitely, since AFAIK only the number of bits differs. I don't know, whether even merging with Real would go to far, though. Kai Burghardt (talk) 01:42, 31 March 2018 (CEST)
If you/we merge single and double, then at least this page should also cover (80-bit) extended. They all are in the IEEE 754 standard, but TP-style real isn't, so one might argue this one could be left out. Anyway, I still think the title of this page no longer describes the content, so it should be renamed. --Bart (talk) 23:41, 31 March 2018 (CEST)
OK, with extended [[Single and Double]] is no option, and [[Single, Double and Extended]] would've been a stupid name. I've moved this article to IEEE 754 formats now. Kai Burghardt (talk) 23:54, 2 April 2018 (CEST)


Example of converting from raw data to double

@Paskal: why AQWord: QWord absolute Result;
Result is a Double, when casting that as a QWord you access undefined memory.
