Generally, they suppress decimal points and leading zeros suppressed. The format specifier line in the beginning specifies the location of the decimal point. it looks something like %FSLAX24Y24 which means A for absolute (as opposed to relative) coordinates, and both X and Y are 2 decimal places, (suppressed decimal point) and 4 fractional places. So, with the above format specifier, X12345 would mean X=1.2345" Apertures are selected with the D word, with a value of 10 or greater. D01 means move to that position. D02 means draw with the current aperture from the current position to the specified position. D03 means flash the current aperture in the specified position.
The apertures are either specified separately (RS274-D) or as part of the beginning of the file (RS274-X). Now, here's where it gets complicated. Since the apertures are usually meant as material saved (copper) and the part that isn't printed at all is material removed, the Gerber file is not very applicable to a process like milling away the blank space between the copper traces and pads. There are "isolation programs" that will collect all touching primitives (lines and pads) and then create a path that surrounds the entire connected net, isolating it from the rest of the board.
