DESCRIPTION

22       These  functions  compute  the complex natural (base e) logarithm of z,
23       with a branch cut along the negative real axis.
24

RETURN VALUES

26       These functions return the complex  natural  logarithm  value,  in  the
27       range  of  a  strip mathematically unbounded along the real axis and in
28       the interval [ -i , +i ] along the imaginary axis.
