In computing, floating-point arithmetic is arithmetic on subsets of real numbers formed by a significand multiplied by an integer power of that base. Numbers of this form are called floating-point num
An early electromechanical programmable computer, the Z3, included floating-point arithmetic (replica on display at Deutsches Museum in Munich).
Leonardo Torres Quevedo, in 1914, published an analysis of floating point based on the analytical engine.
