PROLOG

NAME

       clog, clogf, clogl - complex natural logarithm functions

SYNOPSIS

       #include <complex.h>

       double complex clog(double complex z);
       float complex clogf(float complex z);
       long double complex clogl(long double complex z);

DESCRIPTION

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

RETURN VALUE

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

ERRORS

       No errors are defined.

       The following sections are informative.

EXAMPLES

       None.

APPLICATION USAGE

       None.

RATIONALE

       None.

FUTURE DIRECTIONS

       None.
