Calculation - required rounding?

Might be a stupid question but does the CFAI have in writing what calculation rounding is acceptable?

issue for example:

calculate 1% weekly VaR - from 2011 exam.

I have all the calculations right but use the VaR from my calculator that has many more digits than the rounded number used by CFAI

their solution is 58,916,080

vs mine 58,892,400.

again - sorry for this stupid question but it would be worse not getting points on a question for not rounding correctly

They will not bring down your score for rounding as long as it is reasonable. Personally I neither round results in steps nor the final score.
