+.SH DESCRIPTION
+These functions return the hyperbolic sine of
+.IR x ,
+which
+is defined mathematically as:
+.PP
+.nf
+ sinh(x) = (exp(x) \- exp(\-x)) / 2
+.fi
+.SH RETURN VALUE
+On success, these functions return the hyperbolic sine of
+.IR x .
+.PP
+If
+.I x
+is a NaN, a NaN is returned.
+.PP
+If
+.I x
+is +0 (\-0), +0 (\-0) is returned.
+.PP
+If
+.I x
+is positive infinity (negative infinity),
+positive infinity (negative infinity) is returned.
+.PP
+If the result overflows,
+a range error occurs,
+and the functions return
+.BR HUGE_VAL ,
+.BR HUGE_VALF ,
+or
+.BR HUGE_VALL ,
+respectively, with the same sign as
+.IR x .
+.\"
+.\" POSIX.1-2001 documents an optional range error (underflow)
+.\" for subnormal x;
+.\" glibc 2.8 does not do this.
+.SH ERRORS
+See
+.BR math_error (7)
+for information on how to determine whether an error has occurred
+when calling these functions.
+.PP
+The following errors can occur:
+.TP
+Range error: result overflow
+.I errno
+is set to
+.BR ERANGE .
+An overflow floating-point exception
+.RB ( FE_OVERFLOW )
+is raised.
