Why does changing the sum order returns a different result?
... = 0 + 1
= 1
This demonstrates possibly more clearly that the important part is that we have a limited number of significant digits - not a limited number of decimal places. If we could always keep the same number of decimal places, then with addition and subtracti...
What is the printf format specifier for bool?
...n unescaped percent sign might cause your program to blow up (see here for more). Thus, printf("%s", ...) is safer. If you're not doing any actual formatting to begin with, the printf family of functions is overkill and puts() (or fputs() if you need to print to stderr) is preferable because it's mo...

Another way is:
DateTime.UtcNow.ToString("o");

Cron jobs and random times, within given hours
...2,767, and there are 50,400 seconds between 9am and 11pm, it'd be a little more complicated to randomize the seconds as well. Finally, since the start times are random and independent of each other, it's possible (but not very likely) that two or more instances of the script will be started simulta...
