Re: [pure-lang-users] Proposed syntax changes

[Eddie R. <er...@bm...>]

Something bad is happening here for the complex numbers:

 > sqrt (1+:2);
 2.23606797749979*cos (t/2)+:2.23606797749979*sin (t/2)

the angle t is missing.

Another nice way of doing this is:

sqrt (x+:y) = sqrt (0.5*(r+a)) +: sqrt (0.5*(r-a))
              when
                r = sqrt x*x+y*y;
              end;
