Can a string be interpolated to an integer in elixir?


Asked by Hazel Moses on Dec 03, 2021 FAQ



Any Elixir expression is valid inside the interpolation. If a string is given, the string is interpolated as is. If any other value is given, Elixir will attempt to convert it to a string using the String.Chars protocol. This allows, for example, to output an integer from the interpolation: iex> "2 + 2 = #{2 + 2} " "2 + 2 = 4"
Furthermore,
Elixir supports string interpolation, to use a variable in a string, when writing it, wrap it with curly braces and prepend the curly braces with a '#' sign. This will take the value of x and substitute it in y.
Likewise, Strings in Elixir are inserted between double quotes, and they are encoded in UTF-8. Unlike C and C++ where the default strings are ASCII encoded and only 256 different characters are possible, UTF-8 consists of 66536 code points.
In respect to this,
To create a string variable, simply assign a string to a variable − To print this to your console, simply call the IO.puts function and pass it the variable str − The above program generates the following result − You can create an empty string using the string literal, "".
Moreover,
The '<>' operator is used to concatenate strings in Elixir. To concatenate 2 strings,
