acosh(x) computes the inverse hyperbolic cosine of
Fortran 2008 and later
result = acosh(x)
x- the type shall be
The return value has the same type and kind as
x is complex, the imaginary part of the result is in radians and lies between .
program test_acosh real(8), dimension(3) :: x = (/ 1.0, 2.0, 3.0 /) write (*,*) acosh(x) end program
Inverse function: cosh
