Examples
iex> CPF.flex(" 04.4 .8*58().476-08 ")
"04485847608"
iex> " 04.4 .8*58().476-08 " |> CPF.flex() |> CPF.valid?()
trueformat(cpf) View Source
Returns a formatted string from a given cpf.
Examples
iex> 563_606_676_73 |> CPF.new() |> CPF.format()
"563.606.676-73"new(cpf)

new(String.t() | pos_integer()) :: t()
new(String.t() | pos_integer()) :: t()
Initializes a CPF.
Examples
iex> CPF.new(563_606_676_73)
#CPF<563.606.676-73>
iex> CPF.new("56360667673")
#CPF<563.606.676-73>This function doesn't check if CPF numbers are valid, only use this function
if the given String.t or the integer was validated before.
