[ruby-core:103143] [Ruby master Feature#17769] Proposal: numeric coefficient syntax

ruby-core #103143
Issue #17769 has been updated by mrkn (Kenta Murata). `2i` is an imaginary number literal so it is `Complex(0, 2)`. ---------------------------------------- Feature #17769: Proposal: numeric coefficient syntax https://bugs.ruby-lang.org/issues/17769#change-91215 * Author: mrkn (Kenta Murata) * Status: Open * Priority: Normal ---------------------------------------- When we write a mathematical equation, we often omit a multiplication operator between a coefficient and a variable like `2x`. I guess this convention can be useful in computer programming. Practically, Julia employs this notation: ``` julia> 2pi 6.283185307179586 julia> x = 3 3 julia> 2x 6 julia> pi π = 3.1415926535897... julia> 2pi 6.283185307179586 ``` I wrote a proof-of-concept patch to introduce this notation in Ruby. We can write the following with this patch: ``` irb(main):001:0> x = 3 => 3 irb(main):002:0> 2x => 6 irb(main):003:0> def pi = Math::PI => :pi irb(main):004:0> 2pi => 6.283185307179586 ``` ---Files-------------------------------- num_coeff.patch (296 Bytes) -- https://bugs.ruby-lang.org/ Unsubscribe: <mailto:[email protected]?subject=unsubscribe> <http://lists.ruby-lang.org/cgi-bin/mailman/options/ruby-core>
