Question: problem with -pi interpreted as pi.

Hi

I have a problem with the fact that maple not always knows the difference between pi and -pi. Try for example these three lines:

> evalf((-5-2*I)*(exp(-(.999999999*I)*Pi))^(1/2-0.8e-1*I)); 

> evalf((-5-2*I)*(exp(-I*Pi))^(1/2-0.8e-1*I));

> evalf((-5-2*I)*(exp(I*Pi))^(1/2-0.8e-1*I));

They have significantly different results where the line with the exp( - I*Pi) is interpreted as exp(I*Pi).

Is there anyway to avoid this?

I use maple 13

Thanks in advance

Best regards
Brian
