Just to clarify what I'm after: If you plot (-3)^n where n is a set of negative real numbers between 0 and -20 for example, then you get a discontinuos line due to the problem mentioned above with fractional exponents. However, you can compute what the correct absolute value of the the missing poi

Can you determine the sign of the polar form of a complex number?

To compute the absolute value of a negative base raised to a fractional exponent such as: z = (-3)^4.5 you can compute the real and imaginary parts and then convert to the polar form to get the correct value: real_part = ( 3^-4.5 ) * cos( -4.5 * pi ) imag_part = ( 3^-4.5 ) * sin( -4.5 * pi ) |z

negative base raised to fractional exponent

Does anyone know of an approximation to raising a negative base to a fractional exponent? For example, (-3)^-4.1 since this cannot be computed without using imaginary numbers. Any help is appreciated. -- http://mail.python.org/mailman/listinfo/python-list
