Subject: [ruby-talk:9948] smallest non-zero number (and other limits)

is there a ruby method which gives the smallest non-zero number
like that provided by limits.h in c?  e.g., something like
the smallest number which when added to unity yields a number
different from unity.

this question arose from assert_equal_float(expected,actual,epsilon),
i.e., what how should epsilon be set so as to be machine independent?

thanks,
