TAN(<expN>)

-----------------------------------
Returns tangent of a numeric expression.
Return value - Numeric
-----------------------------------

<expN>
        Numeric expression, in radians, from which tangent is returned.  To
convert an angle from degrees to radians, use DTOR().  The number of
decimal places returned by TAN() can be specified with SET DECIMALS.
