You are right.
I find with gforth:
: go 0 do -0.1e neg_big fdrop loop ;
without locals:
utime 100000000 go utime d>f d>f f- 1e-8 f* f. 0.06762074 us  ok for 1e8
times: (67.62 ns)
and with locals:
utime 100000000 go utime d>f d>f f- 1e-8 f* f.   0.09961387 us  ok for
1e8 times: (99.61 ns)
I missused the timing in the previous post.
Thanks for the correction.
