logarithms in ruby - working?

[tester]

Something like this.

Does it requires something else?

use Math.log(num,base)

Nope, not with array that way.

you need to do it with each array element, using 'each' in a oneliner like this:

Code: Select all

output 0,@arr.each_index{|i|@arr[i]=Math.log(@arr[i],2)}

Okay, thanks on that.

There is one problem.
At each restart I get an error (see attached pic) and must retrig the module.

hmm looks like it does the operation on loading, also when you click insideand change space or something it recalculates the array which contains the already processed values, like this the values are getting smaller till they are aout of range (minus)

just put it in an event methode, to only get triggered from input, i think this should solve the problem ( it does here )

I added afterload/dupkicate triggers for input, works too (no error display in schematic).
