COSH(3f)

DESCRIPTION
COSH(X) computes the hyperbolic cosine of X.

STANDARD
Fortran 77 and later, for a complex argument Fortran 2008 or later

CLASS
Elemental function

SYNTAX
X = COSH(X)

ARGUMENTS

X The type shall be REAL or COMPLEX.

RETURN VALUE
The return value has same type and kind as X. If X is complex, the imaginary part of the result is in radians. If X is REAL, the return value has a lower bound of one, cosh (x) q 1.

EXAMPLE
          program test_cosh
            real(8) :: x = 1.0_8
            x = cosh(x)
          end program test_cosh
