That's purely intellectual; if a machine doesn't have doubles in hardware,
softawre emulation is uselessly slow.

That's not true; I use Lua with lua_Number set to "float", and it works fine.
Of course, I have to bear precision in mind when using it, but it's certainly
practical for many uses.

That's an implementation detail; non-programmers don't care how you're
representing times internally. printf("%i.%06i", i/1000000, i%1000000);
(Just responding to points--if you don't need to target a platform
without doubles, there's probably no major benefit either way. I
just prefer the predictability of integers, in addition to needing
to avoid doubles.)
