Ruby string with USD "money" converted to number

Why not remove all non-digit characters before calling .to_i

Example:

"$7,600".gsub(/\D/,'').to_i

And for a floating point number:

"$7,600.90".gsub(/[^\d\.]/, '').to_f

ruby-on-rails ruby currency

You can do:

"$100.00".scan(/[.0-9]/).join().to_f

or to_i if they're only dollars

ruby-on-rails ruby currency

You could use the Money gem

Money.parse("$100") == Money.new(10000, "USD")
