Thank you for your bug report.

The documentation on GMP says:
These functions allow you to work with arbitrary-length integers using the GNU MP library.

Since 2.5 is not an integer, I don't think your example is supposed to work. Also, I can't find the example on the function.gmp-cmp page, so it also does not seem an error in the documentation.
