Probably. But they are simple enough to emulate.
sinh(x) = 0.5*(exp(x)-exp(-x)) cosh(x) = 0.5*(exp(x)+exp(-x)) tanh(x) = (exp(x)-exp(-x))/(exp(x)+exp(-x)) asinh(x) = log(x+sqrt(1+x*x)) acosh(x) = 2*log(sqrt(0.5*(x+1))+sqrt(0.5*(x-1))) atanh(x) = 0.5*(log(1+x)-log(1-x))

Is there any system that doesn't have cosh/atanh/asinh etc?
And/or does anyone object of having them in _math (and therefore in the global namespace)?
