Overview

Signed integer wrapper

This class wraps an Integer value to indicate it was originally stored as a signed integer (Type 6) in Factorio’s Property Tree format.

Examples:

Creating a signed integer

value = SignedInteger.new(42)
value + 1  # => 43 (behaves like Integer)

Negative values are allowed

value = SignedInteger.new(-5)
