COSD — Cosine function, degrees#

COSD(X)#

COSD(X) computes the cosine of X in degrees.

Parameters:: X – The type shall be REAL or COMPLEX.
Returns:: The return value is of the same type and kind as X. The real part of the result is in degrees. If X is of the type REAL, the return value lies in the range -1 leq cosd (x) leq 1.

Standard:

GNU extension, enabled with -fdec-math.

Class:

Elemental function

Syntax:

RESULT = COSD(X)

Example:

program test_cosd
  real :: x = 0.0
  x = cosd(x)
end program test_cosd
