Actually, I'd like to reiterate my original view that num::Zero should be renamed to AdditiveIdentity (bear with me) based on the fact that when mathematicians use the symbol 0 to denote additive identity, the symbol 0 is not read "zero", but as "additive identity".
All the reasoning above applies to renaming num::One to MultiplicativeIdentity as well (as it pertains to symbol 1 denoting multiplicative identity). If those names are too long, the shortened AddIdentity and MulIdentity could be used instead. > On 10 Apr 2014, at 00:06, Tommi Tissari <rusty.ga...@icloud.com> wrote: > >> On 09 Apr 2014, at 23:42, Kevin Ballard <ke...@sb.org> wrote: >> >> The number 0 is the additive identity for numbers.
