 .SH DESCRIPTION
+These functions calculate the complex hyperbolic tangent of
+.IR z .
+.PP
 The complex hyperbolic tangent function is defined
 mathematically as:
-.nf
-
-    ctanh(z) = csinh(z) / ccosh(z)
-.fi
+.PP
+.in +4n
+.EX
+ctanh(z) = csinh(z) / ccosh(z)
+.EE

 .SH VERSIONS
 These functions first appeared in glibc in version 2.1.
