I wrote some template to compute at compile time how many

That works for small number but after i got an error about

Bye,
bearophile
Thanks i will take a look
this one seem to be interesting
http://graphics.stanford.edu/~seander/bithacks.html#IntegerLogLookup
is like i do but use a table than me i used a recursive way. I go
to try it :-)
