Check expr or How can I do math in Tcl, where hyperbolic cosine are invoked...
DKF: Tcl 8.5 includes support for hyperbolic cosines via the cosh() expr function and the tcl::mathfunc::cosh command.
Also:
What: COSH
Where: http://home.t-online.de/home/dshepherd/cosh.htm
Description: Windows shell interface to Tcl and Tk, providing a COM interface.
COSH can be remotely started on any machine via appropriate
Win32 call (uses a COM Class factory). Can be called from
COM automation clients such as Visual Basic and Delphi.

I think it a very poor idea to name a thing (the extension) with a name that has a specific and well known other meaning. I thought I was going off to look at an implementation of hyperbolic cosine in pure Tcl. -PSE
