## What is Binary Brain?

This is an arbitrary-precision binary calculator for iOS and watchOS. It can add, subtract, multiply, or divide two or more binary numbers. It can operate on very large integers and very small fractional values.
	This calculator is, by design, very simple. You can use it to explore binary numbers in their most basic form. It operates on binary numbers (positive and negative).
	Although designed to be simple, it is an excellent educational tool as well. It keeps track of the calculation in order to let the user verify the calculation. It converts automatically and in real time the latest number in decimal and hexadecimal format. It also converts the latest number in IEEE 754 binary32 (Single-precision floating-point format) format (not available in watchOS version).
	This calculator is able to calculate bitwise AND, OR, NAND, NOR, XOR and XNOR operations. Moreover, it is possible to perform bit shift operations (not available in watchOS version).
