This just comes down to math:
You can calculate the log of any base if you have log of any other base.
4D has the command Log (which is a natural log based on e… 2.718 etc). We can
use it to convert logs to any base.
If you want log base 10 do the following:
$x:=100
$log:=Log($x)/Log(10)
ALERT(String($log))
$log will be 2 as expected
If you wanted base 3 log
$x:=81
$log:=Log($x)/Log(3)
ALERT(String($log))
$log will be 4 as expected
