+.SH DESCRIPTION
+These functions return a value equivalent to
+.P
+.nf
+    log (1 + \fIx\fP)
+.fi
+.P
+The result is computed in a way
+that is accurate even if the value of
+.I x
+is near zero.
+.SH RETURN VALUE
+On success, these functions return the natural logarithm of
+.IR "(1\ +\ x)" .
+.P
+If
+.I x
+is a NaN,
+a NaN is returned.
+.P
+If
+.I x
+is positive infinity, positive infinity is returned.
+.P
+If
+.I x
+is \-1, a pole error occurs,
+and the functions return
+.RB \- HUGE_VAL ,
+.RB \- HUGE_VALF ,
+or
+.RB \- HUGE_VALL ,
+respectively.
+.P
+If
+.I x
+is less than \-1 (including negative infinity),
+a domain error occurs,
+and a NaN (not a number) is returned.
+.\" POSIX.1 specifies a possible range error if x is subnormal
+.\" glibc 2.8 doesn't do this
+.SH ERRORS
+See
+.BR math_error (7)
+for information on how to determine whether an error has occurred
+when calling these functions.
+.P
+The following errors can occur:
+.TP
+Domain error: \fIx\fP is less than \-1
+.I errno
+is set to
+.B EDOM
+(but see BUGS).
+An invalid floating-point exception
+.RB ( FE_INVALID )
+is raised.
+.TP
+Pole error: \fIx\fP is \-1
+.I errno
+is set to
+.B ERANGE
+(but see BUGS).
+A divide-by-zero floating-point exception
+.RB ( FE_DIVBYZERO )
+is raised.
