------- Additional Comments From [EMAIL PROTECTED]  2003-11-25 14:06 -------
I agree that the normal sign function is defined as you state 
(http://mathworld.wolfram.com/Sign.html) and has caused me some confusion.  
However, I don't want to simply change this method as other parts of [math] 
depend on this definition.  My plans are as follows:
1. change the name of sign to positiveSign (any other name suggestions?)
2. create a new sign method based on Mathworld.

If there are any objections, let's here them.
