Frame counts are inherently integers, so there's no reason for using real numbers at all. Even with 24 hours of video at 60 fps, the number of frames is well under 10 million. It fits comfortably into a 32-bit integer and needs only seven digits.
What we are seeing is probably just a consequence of FCP code using a C++ default string formatter for a double.

I have just discovered that if a project contains a clip that has more than a million frames (4.6 hours at 60 fps would do it), then numbers like duration, in, out, etc. will be exported in the XML in scientific notation.
Example:
Expected value: <duration>1234567</duration>
Exported value: <duration>1.23457e+06</duration>
Aside from the fact that it messes up everyone who is expecting an integer there is a loss of precision. The difference between 1234567 and 1234570 frames could be important in some contexts.
Is this a known bug?
So, in my opinion, these really should be double precision if they are going to be real numbers.
