In C++, this function is overloaded in <complex> and <valarray> (see complex cosh and valarray cosh).
- Floating point value.
Return ValueHyperbolic cosine of x.
If the the magnitude of the result is so large that it cannot be represented in an object of the return type, the function returns HUGE_VAL, and the value of the global variable errno is set to the ERANGE value.
PortabilityIn C, only the double version of this function exists with this name.
The hyperbolic cosine of 0.693147 is 1.250000.
