Hi all,
Mostly when I do instance.methods.sort in irb, the list contains +@
and -@ what are these methods and how used.
I’ll appreciate if someone helps me with this.

1 is an object of type Integer
1.methods is a method in the Object Integer (which outputs an Array of
methods for the integer) and .sort is a method on an Object of Type
Array (which sorts the contents of the Array)

From the pickaxe book +@ is a unary + operator simply returns the
receivers value and -@ returns the negated value for Numeric Objects
(floats / Integers)
