Converts a string in signed overpunch format to an integer.
If successful, returns a tuple in the form of {:ok, integer}. Otherwise, it
returns :error.
Examples
iex> SignedOverpunch.convert("100{")
{:ok, 1000}
iex> SignedOverpunch.convert("100}")
{:ok, -1000}
iex> SignedOverpunch.convert("00I")
{:ok, 9}
iex> SignedOverpunch.convert("000")
:error
iex> SignedOverpunch.convert("GOTCHA")
:errorConverts a string in signed overpunch format to an integer.
Similar to SignedOverpunch.convert/1, but raises an ArgumentError if the
input provided is not valid signed overpunch.
Examples
iex> SignedOverpunch.convert!("100{")
1000
iex> SignedOverpunch.convert!("100}")
-1000
iex> SignedOverpunch.convert!("00I")
9
iex> SignedOverpunch.convert!("000")
** (ArgumentError) invalid signed overpunch value: 000
iex> SignedOverpunch.convert!("GOTCHA")
** (ArgumentError) invalid signed overpunch value: GOTCHAConverts an integer to signed overpunch format.
If successful, returns a tuple in the form of {:ok, string}. Otherwise, it
returns :error.
Examples
iex> SignedOverpunch.to_s(1000)
{:ok, "100{"}
iex> SignedOverpunch.to_s(-1000)
{:ok, "100}"}
iex> SignedOverpunch.to_s(9)
{:ok, "I"}
iex> SignedOverpunch.to_s("GOTCHA")
:errorConverts an integer to signed overpunch format.
Similar to SignedOverpunch.to_string/1, but raises an ArgumentError if the
input provided is not an integer.
Examples
iex> SignedOverpunch.to_s!(1000)
"100{"
iex> SignedOverpunch.to_s!(-1000)
"100}"
iex> SignedOverpunch.to_s!(9)
"I"
iex> SignedOverpunch.to_s!("000")
** (ArgumentError) invalid integer: 000
iex> SignedOverpunch.to_s!("GOTCHA")
** (ArgumentError) invalid integer: GOTCHA
iex> SignedOverpunch.to_s!(10.0)
** (ArgumentError) invalid integer: 10.0
