Having read through
http://code.jsoftware.com/wiki/Essays/Tolerant_Comparison
(as far as I managed to follow the reasoning)
I tried these examples:
5 (=!.0) %: *: 5
1
5 (=!.0) *: %: 5
0
5 - %: *: 5
0
5 - *: %: 5
_8.88178e_16
(*:&%: - %:&*:) 5
8.88178e_16
and have been wondering since how/why the order of evaluation would
make a difference (having expected it to throw a zero in *both* cases).
I'm aware of the the asymmetric interval boundaries x*1-t ; x%1-t but
can't figure out whether they might be involved in the differing of
results, as the tolerance is set to zero.
Anybody volunteering with a layman's explanation..?
