ACOSD (The GNU Fortran Compiler)

Synopsis:

RESULT = ACOSD(X)

Description:

ACOSD(X) computes the arccosine of X in degrees (inverse of COSD(X)).

Class:

Elemental function

Arguments:

`X`	The type shall either be `REAL` with a magnitude that is less than or equal to one.

Return value:

The return value is of the same type and kind as X. The real part of the result is in degrees and lies in the range 0 \leq \Re \acos(x) \leq 180.

Example:

program test_acosd
  real(8) :: x = 0.866_8
  x = acosd(x)
end program test_acosd
