Maybe a very naive question, but when I code something like:
RDD=RealBallField(256)
RDD(3.1)*RDD(2.1)
I obtain:
[6.510000000000000461852778244065128704839826135899304117285652827862296732064351 +/- 9.03e-80]
as the output. Where does all the noise after the 15th digit come from and how could I get rid of this?
