ACOSD — Arccosine function, degreesACOSD(X) computes the arccosine of X in degrees (inverse of
COSD(X)).
Fortran 2023
Elemental function
RESULT = ACOSD(X)
| X | The type shall either be REAL with a magnitude that is
less than or equal to one. |
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.
program test_acosd real(8) :: x = 0.866_8 x = acosd(x) end program test_acosd
