The existing Ruby methods should already be fast enough for most cases. C macros/functions for accessing the real and the imaginary parts seems fine, but I think not more than that should be exposed for Complex. ---------------------------------------- Feature #15066: Documentation and providing better API for accessing Complex numbers functions in C extensions https://bugs.ruby-lang.org/issues/15066#change-73897 * Author: v0dro (Sameer Deshmukh) * Status: Feedback * Priority: Normal * Assignee: * Target version: ---------------------------------------- Currently there is absolutely no documentation for working with Complex numbers at the level of the C API. Apart from two macros defined [[here](https://github.com/ruby/ruby/blob/trunk/include/ruby/ruby.h#L1079)] for setting the real and imag values of Complex numbers there is no 'official' way of working with Complex numbers at the level of the C API. I propose two things: * Fully document existing Complex number routines. * Provide a robust and efficient API for dealing with complex numbers from C extensions. -- https://bugs.ruby-lang.org/ Unsubscribe: <mailto:ruby-core-request / ruby-lang.org?subject=unsubscribe> <http://lists.ruby-lang.org/cgi-bin/mailman/options/ruby-core>
