How to strip commas from float input?

Question

I have a field -

:Revenue

and it should accept values like 10,000.00, but if I input such value it stores 10 into dat

Answer 1

You can take a String#delete.

"10,000,000.00".delete(',').to_f 
# => 10000000.0

Answer 2

I found the solution after looking at few places and combining few solutions, since I had to use gsub before the linking to model has to be done. so I created the method in my controller and called it before create and update action. and wrote the following code in the method

params[:record][:Revenue] = params[:record][:Revenue].gsub(/,/,"")

Answer 3

Removing commas is pretty simple:

value.gsub(/,/, '').to_f

Keep in mind that European formatting often uses comma as the decimal value separator so your results would be off by a factor of 100 if processing those sorts of numbers.
