[d2n-analysis-talk] Basic ROOT Question

[David Flay]

In order to get my TDC histograms into ns units, I would multiply the
variable by 10^9:

1e+9*L.s2.lt_c[0], for instance.

This works at the command line.  However, it does <not> work if I do this
in a macro:

rootvar.Form("((1e+9)*L.s2.lt_c[%d]):L.s2.la_c[%d]",i,i);

Has anyone come across this??  It seems like a very simple thing, yet a
ROOT search produces nothing (I have found that virtually any search at
the ROOT website is pointless -- it's better to go with Google... but
nothing there either).  I don't recall ever having trouble multiplying
variables by numbers before... any help is appreciated!

Dave
