Testing for equality is problematic. Two computational sequences that
are mathematically equal may well produce different floating-point
values. Programmers often perform comparisons within some tolerance
(often a decimal constant, itself not accurately represented), but that
doesn't necessarily make the problem go away.[citation needed]

thank you,
strange, after restarting it worked. the unexplainable reason is that i loaded the array values
with "soundfiler". after that, "sel" doesn't recognize the values (only after
restarting pd).

hi list,
does anybody know why "sel" doesn't recognize a value from an array?
see attached pd patch, running on pd 0.39
thanx-
