Subject:  random/3 problems?

In gprolog 1.3.1 when I run random/3 with the call below I get integers.
random(1.0,10.0,RANDOM_NUMBER).
The 1.3.1 manual says that if both Base and Max are integers
then Number will be an integer. I assumed this mean an integer
as determined by integer/1 builtin Prolog predicate. ???
The workaround is easy enough with random/1 so this is not critical.
I also found the following calls to random/3 return the same random number:
: randomize,random(1,10,M),randomize,random(1,10,N). M and N are
the same. This was only tested so far on a very old Fedora 2 platform,
Pentium III and I have not had a chance to try it on a more recent version
of Linux, but it doesn't seem right. The actual calls where in two(2)
different goals, not right after each other, as shown above.
