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

Class:

Elemental function

Syntax:

RESULT = ACOSD(X)

Example:

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

Specific names:

Name	Argument	Return type	Standard

`DACOSD(X)`	`REAL(8) X`	`REAL(8)`	GNU extension
