        "to floating points"
        SYNTAX: X = tofl(A)

        A is an expression whose value is an element of Z, Q, R or a
        polynomial over these structures.
        
        X is assigned the value of A over the floating points, rounded 
        to DIGITS digits. 
        
        In order to change the precision to s digits, please type
        "digits = s" where s is a positive single precision number.
        By default, DIGITS = 37.


        Example 1: (correct)

                tofl(2/3)


        Example 2: (correct)

                DIGITS = 50
                tofl(1/7)


        Example 3: (correct)

                tofl(123)


        Example 4: (correct)

                tofl(24342.4234e-8)


        Example 5: (correct)

                tofl( 3*x+1/3 )
