COSD — Cosine function, degrees#
-
COSD(X)#
COSD(X)
computes the cosine ofX
in degrees.- Parameters
X – The type shall be
REAL
orCOMPLEX
.- Returns
The return value is of the same type and kind as
X
. The real part of the result is in degrees. IfX
is of the typeREAL
, the return value lies in the range -1 leq cosd (x) leq 1.
