Hi - I am working with floats and am wondering how I can trim the decimal and trailing zeros on my whole numbers. For instance, whole numbers are being displayed as 1.0, 2.0, 3.0, etc... I would like to remove the decimal and any trailing zeros with out effecting other non-whole number floats (ex. 1.375). Any ideas? Help appreciated. --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.

Maybe you can convert them to integers? my_float = 2.0 my_float = my_float.to_i if my_float == my_float.to_i Pepe On Feb 27, 1:20 am, northband <northb...-Re5JQEeQqe8AvxtiuMwx3w@public.gmane.org> wrote:> Hi - > > I am working with floats and am wondering how I can trim the decimal > and trailing zeros on my whole numbers.

The %g specifier to sprintf will do this automatically: "%g" % 1.0 => "1" "%g" % 1.375 => "1.375" --Matt Jones On Feb 27, 1:20 am, northband <northb...-Re5JQEeQqe8AvxtiuMwx3w@public.gmane.org> wrote:> Hi - > > I am working with floats and am wondering how I can trim the decimal > and trailing zeros on my whole numbers.

And how can I remove the trailing zeros if the value is to be shown in a
text field?
I.e.:
<%= linea_form.text_field :unidades, :id =>
"invoice_line_units", :name
=> "invoice[lines_attributes][#{id_or_index}][units]", :size =>
10 %>
