ACOSD — Arccosine function, degrees#

ACOSD(X)#

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

Parameters

X – The type shall either be REAL with a magnitude that is less than or equal to one - or the type shall be COMPLEX.

Returns

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.

Standard:

GNU extension, enabled with -fdec-math

Elemental function

Syntax:
RESULT = ACOSD(X)
Example:
program test_acosd
  real(8) :: x = 0.866_8
  x = acosd(x)
end program test_acosd
