14.In complex.h
15.Ft double complex
16.Fn clog "double complex z"
17.Ft float complex

21.Sh DESCRIPTION
22These functions compute the complex natural (base e) logarithm
23of
24.Ar z ,
25with a branch cut along the negative real axis.
26.Sh RETURN VALUES
27These functions return the complex natural logarithm value,
28in the range of a strip mathematically unbounded along the
29real axis and in the interval [\-i pi,\ +i pi] along the
30imaginary axis.
31.Sh ERRORS
32No errors are defined.
