@turing-machine-js/library-binary-numbers

A library for the turing-machine-js.

Install

Using npm:

npm install @turing-machine-js/library-binary-numbers

or using yarn:

yarn add @turing-machine-js/library-binary-numbers

A concept

Binary numbers are represented as a sequence of symbols 0 and 1.

A representation of a number starts with symbol ^ and ends with symbol $.

For example:

• ^$ stands for 0
• ^1$ stands for 1
• ^10$ stands for 2
• ^11$ stands for 3
• etc.

There is no ability to work with negative numbers at this time.

This library provides following objects to work with binary numbers:

• getTapeBlock - this function returns a TapeBlock class instance. It has only one tape. An alphabet of the tape contains the following symbols: space as a blank symbol, ^, $, 0 and 1.
• states - following States class instances which represent some algorithms:
  • goToNumber - move the head to the number's end
  • goToNextNumber - move the head to the next number (to the right)
  • goToPreviousNumber - move the head to the previous number (to the left)
  • deleteNumber - delete the current number
  • goToNumbersStart - move the head to the number's start
  • invertNumber - change every symbol in the number to it's opposite one (0 to 1 and 1 to 0)
  • normalizeNumber - delete leading zeros
  • plusOne - add 1 to the number
  • minusOne - subtract 1 from the number

If you want to use states which were described earlier, you must use a tape block received from the getTapeBlock function.
