8.74 COSD — Cosine function, degrees

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

This function is for compatibility only and should be avoided in favor of standard constructs wherever possible.

Standard:
GNU extension, enabled with -fdec-math.
Class:
Elemental function
Syntax:
RESULT = COSD(X)
Arguments:

X The type shall be REAL or COMPLEX.

Return value:
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.
Example:
          program test_cosd
            real :: x = 0.0
            x = cosd(x)
          end program test_cosd
