Abstract: We start with a mathematical definition of a real interval as a closed, connected
set of reals. Interval arithmetic operations (addition, subtraction, multiplication and
division) are likewise defined mathematically and we provide algorithms for computing
these operations assuming exact real arithmetic. Next, we define interval arithmetic
operations on intervals with IEEE 754 floating point endpoints to be sound and
optimal approximations of the real interval operations and we show that... (Update)
...which has been designed with careful attention to soundness. The underlying interval arithmetic algorithms have been proved correct [14, 13], and we are preparing a proof of the correctness of the contractors for the special functions (exp, log, sin, etc. 4 Higher level...
.... to evaluate an arithmetic expression on floating point numbers is guaranteed to contain the mathematical result of that evaluation [9]. Multiple precision arithmetic is also sometimes used in Interval arithmetic systems. For example, in [10] a C toolbox is described...
