Floating Point Numbers

چکیده
The natural arithmetic operand in a computer is the binary integer. However, the range of numbers that can be represented is limited by the computer’s word size. We cannot represent very large or very small numbers. For example, in a computer with a 32 bit word, the largest signed number is 2 – 1. The range is further diminished if some bits of the word are used for fractions. There are techniques for performing integer arithmetic on groups of two or more words, but these are both painful for the programmer and consuming of CPU time.

The Unum Number Format: Mathematical Foundations, Implementation and Comparison to IEEE 754 Floating-Point Numbers
This thesis examines a modern concept for machine numbers based on interval arithmetic called 'Unums' and compares it to IEEE 754 floating-point arithmetic, evaluating possible uses of this format where floating-point numbers are inadequate. In the course of this examination, this thesis builds theoretical foundations for IEEE 754 floating-point numbers, interval arithmetic based on the project...
متن کاملDesign and Implementation of Complex Floating Point Processor Using Fpga
This paper presents complete processor hardware with three arithmetic units. The first arithmetic unit can perform 32-bit integer arithmetic operations. The second unit can perform arithmetic operations such as addition, subtraction, multiplication, division, and square root on 32-bit floating point numbers. The third unit can perform arithmetic operations such as addition, subtraction, multipl...
متن کاملA Parameterized Floating-Point Formalizaton in HOL Light
We present a new, open-source formalization of fixed and floating-point numbers for arbitrary radix and precision that is now part of the HOL Light distribution [10]. We prove correctness and error bounds for the four different rounding modes, and formalize a subset of the IEEE 754 [1] standard by gluing together a set of fixed-point and floating-point numbers to represent the subnormals and no...
متن کاملComparison of Adders for optimized Exponent Addition circuit in IEEE754 Floating point multiplier using VHDL
Floating point arithmetic has a vast applications in DSP, digital computers, robots due to its ability to represent very small numbers and big numbers as well as signed numbers and unsigned numbers. In spite of complexity involved in floating point arithmetic, its implementation is increasing day by day. Here we compare three different types of adders while calculating the addition of exponent ...
متن کاملEasy Accurate Reading and Writing of Floating-Point Numbers
Presented here are algorithms for converting between (decimal) scientific-notation and (binary) IEEE-754 double-precision floating-point numbers. These algorithms are much simpler than those previously published. The values are stable under repeated conversions between the formats. The scientific representations generated have only the minimum number of mantissa digits needed to convert back to...
متن کاملSolving Range Constraints for Binary Floating-Point Instructions
We present algorithms that solve the following problem: given three ranges of floating-point numbers Rx, Ry , Rz , a floating-point operation (op), and a rounding-mode (round), generate three floating-point numbers x̄, ȳ, z̄ such that x̄ ∈ Rx, ȳ ∈ Ry , z̄ ∈ Rz , and z̄ = round(x̄ op ȳ). This problem, although quite simple when dealing with intervals of real numbers, is much more complex when consider...
