8.74 COSD — Cosine function, degrees

Description:

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

Standard:

Fortran 2023

Class:

Elemental function

Syntax:

RESULT = COSD(X)

Arguments:

`X`	The type shall be `REAL`.

Return value:

The return value is of the same type and kind as X and 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
