Comment(by rwh):

 Thanks for taking the time to report this!

 The '=' operator is in general used to compare. An answer is generated
 when enter is pressed. However, the error-reporting in this case ''was''
 really poor. I improved this by mentioning that a number or variable is
 expected. sin(pi)=0 returns False because by default the sine function
 interprets the argument in degrees; use of radians can be toggled in the
 'Format' toolbar. sin(pi)=0 will, unfortunately, still return False due to
 finite precision.

 There was indeed a parenthesis bug when evaluating things like 0(5); I
 fixed this to return an error.

 I cannot reproduce the problem with 2^2=4 returning False. In fact I can't
 reproduce any of the exponent bugs, so it might be build-related. Which
 build are you on?

 Jim, putting this is update.1 will have to include some new error
 messages, because I don't have a general 'Parse error' message available.
 Do you still want this in?
