SYNTAX
x = cosh(x)
DESCRIPTION
cosh(x) computes the hyperbolic cosine of 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) >= 1.
EXAMPLE
Sample program:
program demo_cosh real(8) :: x = 1.0_8 x = cosh(x) end program demo_cosh
STANDARD
[[FORTRAN 77]] and later, for a complex argument [[Fortran 2008]] or later
CLASS
