+NAME
+    sinh - hyperbolic sine
+
+SYNOPSIS
+    sinh(x [,eps])
+
+TYPES
+    x		real
+    eps		nonzero real, defaults to epsilon()
+
+    return	real
+
+DESCRIPTION
+    Calculate the sinh of x to the nearest or next to nearest multiple of
+    epsilon, with absolute error less than .75 * abs(eps).
+
+    sinh(x) = (exp(x) - exp(-x))/2
+
+EXAMPLE
+    > print sinh(1, 1e-5), sinh(1, 1e-10), sinh(1, 1e-15), sinh(1, 1e-20)
