Shud we adjust the no. of decimal places to 6? setting, correct, another, adjusted, calculator

I have the no. of decimal places adjusted to 4 in my TI BA plus calculator. I recall that L1 schweser suggested setting it to 4 places.

However, today while attempting some schweser questions, I couldn't drill down to the correct answer coz of the rounding off issue. I think there was another thread where someone got a v diff answer coz of the same issue.

Should we adjust the no. of decimal places to 6 or 8?
