From: "mrkn (Kenta Murata)" Date: 2021-09-22T01:44:51+00:00 Subject: [ruby-core:105365] [Ruby master Feature#18179] Add Math methods to Numeric Issue #18179 has been updated by mrkn (Kenta Murata). I'm negative to this proposal. I don't think `Math.sqrt` is the behavior or the property of a Numeric object. It is the positive square root function that maps from/to the set of non-negative real numbers. If we introduce `Numeric#sqrt`, we should expand its domain to negative numbers and Complex numbers. Also, it is better to consider other kinds of numbers, such as Quaternion. ---------------------------------------- Feature #18179: Add Math methods to Numeric https://bugs.ruby-lang.org/issues/18179#change-93779 * Author: ankane (Andrew Kane) * Status: Open * Priority: Normal ---------------------------------------- Hi, I wanted to get thoughts on adding class methods from `Math` as instance methods on `Numeric`. ```ruby x.sqrt # vs Math.sqrt(x) x.log # vs Math.log(x) ``` Rust takes this approach and it (subjectively) feels more intuitive/object-oriented. It also seems more consistent with methods like `x.abs`. -- https://bugs.ruby-lang.org/ Unsubscribe:
