I'm not sure if I completely understand your question, but from my interpretation, the answer is #170#.

Explanation:

Your number is #169.948#.

Whole numbers are to the left of the decimal #(169)#.

Look at the FIRST NUMBER to the right of the decimal (#9# in the #.948#).

Rounding Rules:

  • Less than 5 #-># ROUND DOWN
  • Greater or equal to 5 #-># ROUND UP

Since #9# is larger than #5#, you have to round the #9# in #169# UP.

However, the next number after #9# is #10#.

This means you must round the #6# in #169# UP to #7# and put a #0# instead of the #9#..

You should get #170# as your answer.

This makes sense because #170# is after #169#.
