min/max filtering (array)

[Nubeat7]

array = [-1,0.0,90,50,100,150,200]

min = 0.0 ;
max = 100 ;

(array.map {|v| (min..max) === v ? v : nil }).compact

smart! already met the "case equality operator" few times, but never knew where/how to use..

I still can't get a result from this...

Code: Select all

def event i,v
  if i == 0 then
    minVal = 0.5
    maxVal = 1
   a = @txt.map{|item|item*maxVal-minVal+minVal}
   output 0,a
  end
end

I see I opened a headache maker.

Posting schematized ("green prims" compatible so to speak) idea provided by Tronic, in case someone with my (equall-or-less)skills looks for such thing.

Seems to work fine, and looks elegant. Thanks!

i think a combination of tronics version and mine would be the shortest and fastest

Code: Select all

output @yourarray.keep_if{|x|(min..max) === x}

i`m @ work, so not tested

This break the result of array if the next value not match the min/max range.

hmm strange i tried it here:
http://www.compileonline.com/execute_ruby_online.php

Code: Select all

array = [5,1,3,4,1,6,7,8,9]
array.keep_if{|x|(2..7) === x}
puts array;

and it puts:
5
3
4
6
7

so it shoul be right?

Yes work
