Variables

var ErrAdditionOverflow = errors.New("addition overflow")

ErrAdditionOverflow is raised when there is an overflow because of the addition of two numbers

var ErrMultiplicationOverflow = errors.New("multiplication overflow")

ErrMultiplicationOverflow is raised when there is an overflow because of the multiplication of two numbers

var ErrSubtractionUnderflow = errors.New("subtraction underflow")

ErrSubtractionUnderflow is raised when there is an underflow because of the subtraction of two numbers

Functions
