Exponentiation Binary "**" is the exponentiation operator. It binds even more tightly than unary minus, so -2**4 is -(2**4), not (-2)**4. (This is implemented using C's pow(3) function, which actually works on doubles internally.) > -----Original Message----- > From: Prachi Shroff [mailto:[EMAIL PROTECTED]] > Sent: Wednesday, May 22, 2002 9:53 AM > To: [EMAIL PROTECTED] > Subject: power of > > > Hi! > > This may sound as a very stupid question, but here it comes > anyways.
