I'm a little confused by: (i) the definition of the modulus and floor division functions for complex arguments; (ii) the fact that these functions for complex arguments are now "deprecated"; and (iii) the fact that the math.floor() function is not defined at all for a complex argument.
If I were thinking about this from scratch (in the context of mathematics, rather than any particular programming language), I /think/ I would be naturally inclined to define: floor(x + yj) = floor(x) + floor(y)j for all real x, y z % w = z - floor(z / w) * w for all complex z, w (!= 0) These seem like they would be mathematically useful definitions (e.g. in algebraic number theory, where one has to find the "nearest" Gaussian integer multiple of one Gaussian integer to another - I forget the details, but it has something to do with norms and Euclidean domains), and I don't understand why Python doesn't do it this way, rather than first defining it a different way (whose mathematical usefulness is not immediately apparent to me) and then "deprecating" the whole thing! It seems like a wasted opportunity - but am I missing something? Has there been heated debate about this (e.g. in the context of Python 3, where the change to the division operator has apparently already provoked heated debate)? Also, by the way, is there some obvious reason for Python's use of the notation x + yj, rather than the more standard (except perhaps among electrical engineers) x + yi? -- Angus Rodgers _______________________________________________ Tutor maillist - Tutor@python.org http://mail.python.org/mailman/listinfo/tutor
