Hi,
Am i doing something silly here in expecting Euler's
formula to be handled by exp? exp( ix ) = cos x + i sin x.
The first example below follows this, the others not.
Thanks for the education!
> exp( complex(real = 0, imag = 2*pi) )
[1] 1-0i
> exp( complex(real = pi, imag = 2*pi) )
[1] 23.14069-0i
> exp( complex(real = pi/2, imag = 0) )
[1] 4.810477+0i
