Declare Function Cos ( ByVal angle As Double ) As Double

result = Cos( angle )

angle

Returns the cosine of the argument angle as a Double within the range of -1.0 to 1.0.

The argument number is measured in radians (not degrees).

The value returned by this function is undefined for values of angle with an absolute value of 2 ^ 63 or greater.
