    Hi,<br>
    <br>
    I've found that Scheme48 prints the results of dividing one integer
    by another in a fraction notation. So, I tried the function
    'rational?', which returns true when the operand is a number, even
    if it is a known irrational one.<br>
    Following are some results:<br>
    <blockquote type="cite">(rational? (sqrt 2))<br>
    </blockquote>
    #t<br>
    <blockquote type="cite">(rational? (exp 1))<br>
    </blockquote>
    #t<br>
    6&gt; (define pi (* 2 (asin 1)))<br>
    ; no values returned<br>
    6&gt; pi<br>
    3.141592653589793<br>
    6&gt; (rational? pi)<br>
    #t<br>
    <br>
    Is it supposed to work this way?<br>
    <br>
