In my app i get data from csv and in some fields of quantities value is 100> and etc. But how to check that? and select only integer(float) part? But note! it can be <20, >30, 30< and so over.

Answer 1

If you have floating point numbers (not just the integer part), you can use a small variant of Justin Ko’s solution:

values = ["10.1>", "<20.3", ">30.4", "30.6<"]
values.each do |val|
  puts /(\d+\.\d+)/.match(val)[0].to_f
end

# => Output will be 10.1 20.3 30.4 30.6
