.SH Description
These functions compute the designated hyperbolic functions for 
double and float data types.
.SS Error
Below 2.4 
.I ulps 
(unit in the last place).
.SH Diagnostics
The
.PN sinh 
and 
.PN cosh 
functions return
+\(if
(and
.I sinh\^
may return
-\(if
for negative
.IR x )
if the correct value would overflow.
