[lmi-commits] [lmi] master 140c288 05/14: Remove dead code [304]

[Greg Chicares]

branch: master
commit 140c28829a95107bb5147d68b0f7130433984fbe
Author: Gregory W. Chicares <gchicares@sbcglobal.net>
Commit: Gregory W. Chicares <gchicares@sbcglobal.net>

    Remove dead code [304]
    
    See '7702.html' [14.3/5]. This difference:
      (LoadTgt[t] − LoadExc[t]) × aD[t]
    had been calculated and stored, but never used. It would have been used
    in Irc7702::CalculatePremium(), where it's just a scalar subtraction,
    which is not so costly as to justify calculating and storing the
    difference for every possible index t.
