Precision in mathematica

Question

I am having some trouble with mathematica, i need to precise calculations and he is rounding my numbers and taking decimal cases from them and i wanted to know if there's a way i can tell him to stop or only do that for some specific lenght of numbers, for example if we have $0.0119935,0.0561,0,084942$ and add them up the result should be $0,1530355$ and mathematica gives me $0.153036$. Is there a way i can change this ? Thanks in advance.

expr = 0.0119935 + 0.0561 + 0.084942 displays as
0.153036

The output display (menu: Mathematica | Preferences | Displayed precision) is rounded to six (default) decimal places; however, the internal value is not rounded. To see the internal value look at the FullForm:

expr // FullForm displays as

I think you can solve this issue by using SetPrecision.

I hope that helps!
