ps -axo user,%cpu,%mem - most processes using 0% of memory

Hi!
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.

I attach patch to correct this
