It's an under-specification in the definition of the PostScript
language, which doesn't require integral reals to print with a
decimal point.
>From a compatibility viewpoint, it's a bug in Ghostscript. I'll make
reals always print with a decimal point (or an exponent) when I
re-release 2.5.1. I can't, however, guarantee that Ghostscript will
print all reals the same way that an Adobe interpreter does.
