[Rivet] rev. 890 broke CDF_2008_DRELLYAN

[Hendrik Hoeth]

Hi,

I received updated numbers and cuts for the CDF underlying event
analysis in Drell-Yan events. When I changed the analysis I realized
that the CDF_2008_DRELLYAN is broken since revision r890.

Andy, do you have any idea what could be going on here? It seems to be
related to the changes you made to the math classes.
