A164003: Decimal expansion of
.
-
One has to be careful about branches of
multivalued complex functions. By definition
is
(using any of the branches of the logarithm function)
= e π i (1 + π i / 2 + 2 n π i ) |
(for any integer
)
= − (e − π 2 / 2 − 2 n π 2 ) |
. There is no imaginary part in any of its branches. If
we get
times the present constant.
