Re: [Pharo-project] no Complex class in Pharo?

Stef, One thing that must not happen is "automatic" use of complex numbers. Things like -1 sqrt should raise an error. If one wants a complex result, then -1 asComplex sqrt would be a nice choice. That way, one can choose whether or not complex numbers are viable - many times, they are not wanted.

excellent marcus could you change (unstable by alpha) for 1.4 because 1.4 is stable :) On Mar 24, 2012, at 8:20 PM, Marcus Denker wrote: > Hi, > > Instead of the cryptic "shortcuts" section, the main page now has a download section: > > > http://www.pharo-project.org > > -- > Marcus Denker -- http://marcusdenker.de > >

Was this done just for streamlining, or are there known bugs in the implementation of Complex in Squeak? L.

[Pharo-project] speeding up BigNum/Fractions calculations using NativeBoost?

by Lawson English

I'd like to see how fast a Mandelbrot Set algorithm could be implemented in Squeak/Pharo by using NativeBoost to bypass the VM whenever possible. Is that a worthwhile optimization, do you think? Lawson
