Split string Ruby on Rails based on number of characters -

-

मैं इन नंबरों को विभाजित करना चाहता हूं 

  a = 900000 b = 1800000 c = 5000 <  
 एक [0] = 900  
 एक [1] = 000  
 ख [/ code>  
 इन में  
 
 एक [ 0] = 1800  
 b [1] = 000  
 c [0] = 5  
 सी [1] = 000   
 मैं यह कैसे कर सकता हूं?   
 
 
 श्रेणी के साथ प्रयोग:  
  a = 1800000 [a.to_s [0 ... -3], ए.टी.ओ.एस [-3 ..-1]] # = & gt; ["1800", "000"]  
 
 का उपयोग करना 
 
  a.divmod (1000) # = & gt; [1800, 0] ए.डि_मॉड (1000) .मैप {| n | | '% 03d'% n} # = & gt; ["1800", "000"]  
 
 नियमित अभिव्यक्ति का उपयोग करना: 
 
  a.to_s.match (/ (। *) (। {3} ) $ /)। कब्जा # = & gt; ["1800", "000"]
