I was wondering if there is a consensus about the precision of the data output by YT should be?<div><br></div><div>I&#39;ve came upon this question when trying to output ellipsoidal parameters along with halo attributes.  With the current setting, the halo attributes are outputted with 9 decimal points, but the ellipsoid parameters determined using the particle&#39;s position (when the data is 64 bit) has 16 decimals.  </div>
<div><br></div><div>I was thinking that it is best to keep whatever precision we have, but Stephen brought up a good point, that the halos are only vaguely defined, that the extra digits are a waste of storage.  So I just want to see if anyone even cares, and what we want to go with.  Either way, I think it is best to be consistent across the board, having both halo or ellipsoid IO in the same amount of decimals.</div>
