acosh(3f) - [FORTRAN:INTRINSIC:MATHEMATICS:TRIGONOMETRIC] Inverse hyperbolic cosine function
result = acosh(x)
ACOSH(X) computes the inverse hyperbolic cosine of X.
X the type shall be REAL or COMPLEX.
The return value has the same type and kind as X. If X is complex, the imaginary part of the result is in radians and lies between0 <= AIMAG(ACOSH(X)) <= PI.
Sample program:
program demo_acosh implicit none real(8), dimension(3) :: x = [ 1.0, 2.0, 3.0 ] write (*,*) acosh(x) end program demo_acosh
