Hey there,

I need to write an expression that will assign values to a sequence of ratios (2:1) so, e.g. 2, 4, 8, 16, 32. How would I make a function that would convert 2 into 1, 4 into 2, 8 into 3 and so on? I need to do this for numbers reaching into the thousands.

Cheers!

just to reiterate, these ratios are not fixed, I need to convert them into floats, not integers. (e.g. 2 = 1, 3 = 1.5, 4 = 2, etc)

damn... my highschool maths was rustier than i thought. Had to look up wikipedia.

http://en.wikipedia.org/wiki/Logarithm#Change_of_base

pd gives you the [log] object for base e, so you need to divide by the log of 2 to get base 2 (which is what you are asking for)

basically:

[(your number).....
|
| [loadbang]
| |
[log] [2 (
| /
| [log]
| /
[/ ]
|
|
[(the answer).......

That did the trick alright! Thanks a bunch fella!
