No, ttuner, when a temperament is specified using cents (not the usual 
method with this tuner) uses a floating point number. You can specify to 
any sane degree of precision, though there's no point to using more than 
a couple of digits past the decimal, of course! Same goes for specifying 
the original frequency - you can set it to 415, or 415.3, or 
415.288888884 if you want.

No idea where you're getting +/- 0.5 cent from. Maybe you're thinking of 
another app?

(BTW, I wrote the original ttuner program that the app is based on...)

I'm really confused by what you might mean by "cent deviation is 
different depending on the octave".. A tuner that gave different values 
for different octaves wouldn't be very useful, would it?  I think maybe 
you're talking about something completely different than I am...
