Hi there, > Are you asking whether a shell script can handle complex arithmetic? What does that have to do with Sage? Maybe it's just wishful thinking. One day, SageMath may have it's own shell (smiley)
> If that's not what you're asking, please clarify. Maybe just another wishful thinking, how to make [ 1 = 1+0i ] evaluate to 'true' with a tiny bit (0) of imaginary part (smiley) Thank you for your help, it is much appreciated.
