fractional number

    Dear members of MathGroup,
    I have a trouble manipulating Mathematica.
 
My trouble is as follows:
Consider a fractional number and transform it into decimals.  In this case,
there could be left many decimals.  Then, I need to round the third decimal
point as follows:
    If they are larger than six digits, it should be rounded up from the
third decimal points and rounded off if smaller than five.
    Take examples;
    1/17= 0.05882...  the fractional number should be expressed as 0.06.
    1/18= 0.0555...   the fractional number should be expressed as 0.05.
 
    I'd like to know how to program Mathematica to depict the above story.
 
    I hope to receive answers from you soon.
 
        Sincerely,
        Fujio Takata
 
        P.S. My e-mail address; JikaiRF at aol.com
