Found it quite nice to work with, to get the bar you just:
int bar = (int) floatBeatPercent;
while to get the percent you:
float percent = floatBeatPercent - ((int)floatBeatPercent);
In C you mention "bar" as int, and "beat" as float, I presume you
want
to use the decimal part of the float to show "progress" trough that
beat? Thinking about very slow BPM's.. that could become important.
Interesting, I hadn't considered just a value in bars. Not having beats
at all seems strange. The complete independence from time signature is
sort of nice, though.
The problem with that is the precision of exact beats is pretty fuzzy.
Particularly for e.g. 3/4 where beat 1 would be 0.33333....., beat 2 is
0.66666..., etc.
There *is* a lot to be said for a single floating point value, be it
beats or bars (math is so easy), but it seems sort of naive in a way I
can't really justify...

P.S. "Percent" means "out of 100", "fraction" would be
better here. The
value you describe is simply a float with "bars" as the unit.
