Hi guys What I would love is the following: that we get a good Complex package! Since we can do method extensions in Smalltalk we can design a really nice Complex packages with its own tests. We could publish for now Complex into PharoTaskForces or create a PharoExternalPackages or whatever. What do you think? Stef On Aug 12, 2009, at 1:49 AM, Ken.Dickey wrote:

I really can't stand some of the oddities of Complex numbers in Squeak [Note Mantis bug 311 -- http://bugs.squeak.org/view.php?id=3311].
I would find the following to be more rational:
3 asComplex. "no change--> (3+0i)" 3 asComplex isNumber. "no change--> true" -1 asComplex < 1 asComplex. "--> true" -4 sqrt. "--> 2.0i" -3 ln. "--> (1.098612288668382+3.141592653589793i)" ((1/2) + 2.1i) sin arcSin. "--> (0.500000000000001+2.1i)" ((((1/2) + 2.1i) sin arcSin) roundTo: 0.000001) = ((1/2) + 2.1i). "--> true" ((((1/2) + 2.1i) tanH arcTanH) roundTo: 0.000001) = ((1/2) + 2.1i). "--> true"
Attached is a change set which adds a number of tests for Complex and the changes for Complex which allow those tests to pass in Pharo1.0beta update: #10413. Note that Complex becomes a subclass of Magnitude.
I thought it would be useful to post the code first for your thoughts and any code cleanups. As an occasional Smalltalk user, you may wish to correct some of my idioms. Please forgive an old newbie.
