Is there something special about the number 65535?
2¹⁶-1 & 2⁵ = 2⁵ (or? obviously ?)
Implementing base-10 floating point division
I’m implementing floating-point arithmetic, for a micro-controller which does not support floating point numbers, in either hardware or software.
(Software being “written” in a sort of electrical diagram program.)
I’ve finished encoding/decoding from/to integers, adding, subtracting, and multiplication.
My “floats” are represented as C * 10^E, where:
Why do some software packages have an “amd64” suffix for 64-bit systems?
When downloading various software packages, and executables for Windows, I always see two different types of executables to download. One just says ...32-bit and the other always says ...amd64. I know this has nothing to do with AMD, but it is referring to 64-bit operating systems, so why is this still a norm? Even large companies like Google and Ubuntu have packages set up like this.

Importance of uniformity of development architecture across the team
If some developers still use a 32 bit ‘Windows XP’ and others use a ’64 bit Windows 7′, would it be advisable for the entire team to work with 32 bit development tools even if their OS is 64 bit? Are there any problems that could happen if uniformity is not followed?
Using error numbers which only work on 64 bit servers: a bad idea?
In an attempt to solve one problem I encountered another. I would like to have an easy and memorable way of creating unique error numbers, across projects and across developers. The scheme I came up with was to use the initials of the developer, find their position in the alphabet, and append the date and time.
Example: lets say the developer Mark Elliot Zuckerberg (initials MEZ) writes code that throws an exception on Feb 8th 2014 at 12:54AM. The error code would be: 8526020820140054
Why might it be difficult to make a 64 bit version of a program?
In my short time programming, it has been trivial to compile any of my C++, Java, etc. for either a 32 or 64 bit machine so long as I have the full source for the program.
