have you tried typing “log” into an object box yet?

]]>newobj: log: No such object]]>

i did however dig out a text book from uni (!) and found this useful rule:

logA(x) = logB(x) / logB (a)

[capitals are meant to be subscript]

so, i can do it in [expr] with log to the base 10

[expr log(($f1)*($f2-1)+1)/log($f2)]

this is for a range of 0. 1.

for other ranges just scale before and after.

frustrating, that expierience when typing “log” into an

object box, isnt it?

]]>formula, you might end up with something like this:

[expr ((log((($f1-$f2)/($f3-$f2))*($f4-1)+1)/log($f4))*($f3-$f2))+$f2]

where $f2 $f3 are range low range high, and $f4 is the base.
