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

You may also want to make sure that your code localizes correctly  or make sure the users are used to the  international  notation  For example   1 112  actually means different numbers across different countries  In Germany it means the number a little over one  instead of one thousand and something   Corresponding Wikipedia article is at http   en wikipedia org wiki Decimal mark  It seems to be poorly written at this time though  For example as a Chinese I m not sure where does these description about thousand separator in China come from

The following is another method that will work  although as with some of the other methods it will strip decimal places   a   1 112 b   a scan   d    join   to i   gt  1112

I would do using String tr     1 112  tr         to i     gt  1112

Some more convenient   1 1200 00  gsub    0-9          it makes  1 200 200  work properly aswell
