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
