  24. .SH DESCRIPTION
  25. The functionality described on this reference page is aligned with the
  26. ISO\ C standard. Any conflict between the requirements described here and the
  27. ISO\ C standard is unintentional. This volume of POSIX.1\(hy2017 defers to the ISO\ C standard.
  28. .P
  29. These functions shall compute the complex natural (base
  30. .IR e )
  31. logarithm of
  32. .IR z ,
  33. with a branch cut along the negative real axis.
  34. .SH "RETURN VALUE"
  35. These functions shall return the complex natural logarithm value, in
  36. the range of a strip mathematically unbounded along the real axis and
  37. in the interval [\-\fIi\fR\(*p,\ +\fIi\fR\(*p] along the imaginary
  38. axis.
