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
