## Feature #10641

Updated by prijutme4ty (Ilya Vorontsov) over 6 years ago

Hello, I propose to introduce `Fixnum#finite?` Fixnum#finite? and `Bignum#finite?` Bignum#finite? methods. Use case for this is following: ```ruby Interval = Struct.new(:from, :to) do def finite? from.finite? && to.finite? end end ``` For now # this works: ```ruby works Interval.new(1.5, 1000.0).finite? Interval.new(1.5, Float::INFINITY).finite? ``` But # but this fails due to absence of `Fixnum#finite?`: ```ruby Fixnum#finite? Interval.new(1, 3).finite? Interval.new(1, Float::INFINITY).finite? ``` It looks natural that `Fixnum#finite?` Fixnum#finite? should always return `true`. true. I didn't worked extensively with `Bignum`-s, Bignum-s, but probably `Bignum#finite?` Bignum#finite? should also always be `true`. true.
