    -- Computes the natural logarithm (base e) of x.

    function Exp (X : Float; Base : Float := E) return Float;

    -- Computes BASE raised to power of X.  The base defaults
    -- to "e".
    -- X real
    -- BASE real, but not 0.0

    function Sin (X : Float) return Float;

    -- Computes sine of X in radians.
    -- X real

    function Cos (X : Float) return Float;

    -- Computes cosine of X in radians.
    -- X real


    function Atan (Y : Float; X : Float := 1.0) return Float;

    -- If X = 1.0 (default), the arc tangent of Y is
    -- computed.  The result is in radians and lies in the
    -- interval: -PI/2 <= arc tan <= PI/2.  If X /= 1.0,
    -- the arc tangent of Y/X is returned.  The result
    -- is in radians and lies in the following intervals
    -- depending of the sign of Y:
    --
    --      Y >= 0, X >  0:  0      <=  arc tan <   PI/2
