cosh(3f) - [FORTRAN:INTRINSIC:MATHEMATICS:TRIGONOMETRIC] Hyperbolic cosine function
x = cosh(x)
cosh(x) computes the hyperbolic cosine of X.
X The type shall be REAL or COMPLEX.
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.
Sample program:
program demo_cosh use, intrinsic :: iso_fortran_env, only : real_kinds, real32, real64, real128 implicit none real(kind=real64) :: x = 1.0_real64 x = cosh(x) end program demo_cosh
