log in base 2

[Pietro Raviola]

Hi,

I would like to generate the following variable

gen log_x= log2(x)

where log2 means log in base 2. Is that possible? I found only log and and ln..

There is no dedicated function because you don't need one:

. di ln(1024)/ln(2)
10

It is equal to:
log2(x) = ln(x)/ln(2)

Thanks a lot
