Changing the counter type to double is complicated, since it gives
errors during compilation. It seems I'll have to change it in the
functions which uses it too.
I tried using the Stats::Value, but am getting errors. In the stats used
in src/sim/stat_control.cc, which are of type ::Value, like hostSeconds
(which prints out a double at the end), the stats have some .functor
declared in it, which is doing the calculation. I dont know how this
works, and when it gets called, but I was looking for something simpler.
It's not that complicated. It just calls a function
If I declare my stat as a Stats::Value mystat
and then try doing something like mystat += mystat * time_since_access
Statistics can only be assigned to. You cannot use them in the rhs of an
expression. Can you instead just do:
mystat *= time_since_access + 1;
It should be mathematically equivalent.
Is there a simpler way, with a static variable or another global variable
defined in some top level file. I should be able to use that global
variable to keep storing the values every cycle and finally dump it at the
end (maybe assign it to some stat at the end?)
Let me ask a more fundamental question. What are you storing that needs
to be a float? In my experience, most things can be expressed as integers
and then you can use a formula to calculate some fractional value.
