Format for displaying float?

Question

I need to display float numerics with symbol "+" or "-" before.

What is the correct string format?

For ex.

-1,5
-1
-0,5
 0
+0,5
+1

  settings.Columns.Add(column =>
          {
              column.FieldName = "current";
              column.Caption = "Numeric";
              column.ColumnType = MVCxGridViewColumnType.SpinEdit;
              var edsettings = column.PropertiesEdit as DevExpress.Web.ASPxEditors.SpinEditProperties;
              edsettings.DisplayFormatString = "0.#";
          });

this is column of devexpress component grid in asp.mvc. where "current" is decimal value in Model

Use the semicolon seperator to define different formats for positive and negative values, for example

string.Format("{0:+0.0;-0.0}", floatValue)

If you don't want to have a sign before a zero, then use a third option:

edsettings.DisplayFormatString = "+0.#;-0.#;0";
