Description admin 2010-02-25 14:50:00 UTC 
Modern computers have a large amount of memory.
But, in ps(1) source I see:
(void)printf("%*.1f", v->width, getpcpu(k));
(void)printf("%*.1f", v->width, getpmem(k));
0.1% - it very big.
for 8Gb ram it = 8mb
Many of the processes is less than this number.

Fix: see patch

I've looked into this. The change inevitably adds more characters to output (mostly replacing 0.0 with 0.00) and I can see someone feeling that it'd be less readable. Personally, most of the time I don't need more precision than the current default of .1 yields -- and if I wanted, I'd probably be satisfied using -o rss instead.
