[ruby-core:65903] [ruby-trunk - Feature #10425] A predicate method to tell if a number is near another

ruby-core #65903
Issue #10425 has been updated by Martin D=C3=BCrst. Such a predicate would indeed be convenient. But sometimes, one doesn't wan= t to compare with an absolute epsilon, but relatively, e.g. like so: ((other.abs.to_f + abs.to_f) / (other.to_f - to_f).abs) <=3D ???? ---------------------------------------- Feature #10425: A predicate method to tell if a number is near another https://bugs.ruby-lang.org/issues/10425#change-49642 * Author: Tsuyoshi Sawada * Status: Open * Priority: Normal * Assignee:=20 * Category:=20 * Target version:=20 ---------------------------------------- A method `near?` like the following would be useful. ~~~ruby class Numeric def near? other, delta: Float::EPSILON (other.to_f - to_f).abs <=3D delta.to_f end end class Time def near? other, delta: Float::EPSILON to_f.near?(other.to_f, delta: delta) end end ~~~ It can be used to check errors, or whether something is around something. ~~~ruby 23.24324.near?(23.23, delta: 0.5) # =3D> true t1 =3D t2 =3D Time.now t3 =3D Time.now t1.near?(t2) #=3D> true t1.near?(t3) #=3D> false 5.near?(3, delta: 1) #=3D> true ~~~ Some testing frameworks have something similar to this, but I think this is= an elementary concept that Ruby should support at it core. --=20 https://bugs.ruby-lang.org/
