COSH intrinsic function

Standard: F77 F90 F95 F2003 F2008 F2018 Example program


COSH ( X )

X : Real or Complex;

Result : Same type and kind as X.


The value of the result is an approximation to the hyperbolic cosine of X. Like many intrinsic functions, this is elemental; the result has the same shape as X, with the operation being applied elementwise.

If X is of type Complex, its imaginary part is an angle in radians. Note that COSH(X) is identical to COS((0,1)*X).
