Convert string with comma to integer

Question

Is there any neat method to convert \"1,112\" to integer 1112, instead of 1?

I\'ve got one, but not neat:

\"1,112\".split(\',\').join.to_i #=> 11         


        

Answer 1

If someone is looking to sub out more than a comma I'm a fan of:

"1,200".chars.grep(/\d/).join.to_i

dunno about performance but, it is more flexible than a gsub, ie:

"1-200".chars.grep(/\d/).join.to_i
