Decimal Floating-Point: Algorism for Computers
نویسنده
چکیده
Origins of decimal arithmetic • Decimal (base 10) arithmetic has been used for thousands of years • Algorism (Indo-Arabic place value system) in use since 800 AD • Many early computers were decimal Decimal computation today • Pervasive in financial, commercial, and human-centric applications – often a legal requirement • Benchmarks do not reflect actual use • 55% of numeric data in databases are decimal (and a further 43% integers)

Design Exploration for Decimal Floating-Point Arithmetic
Commercial applications and databases typically store numerical data in decimal format. Currently, however, microprocessors do not provide instructions or hardware support for decimal floating-point arithmetic [ 1 ]. Consequently, decimal numbers are often read into computers, converted to binary numbers, and then processed using binary floating-point arithmetic. Results are then converted back...

متن کاملIEEE Standard 754 Floating-Point
There are several ways to represent real numbers on computers. Fixed point places a radix point somewhere in the middle of the digits, and is equivalent to using integers that represent portions of some unit. For example, one might represent 1/100ths of a unit; if you have four decimal digits, you could represent 10.82, or 00.01. Another approach is to use rationals, and represent every number ...
متن کاملParallel Implementation of Multiple-Precision Arithmetic and 1, 649, 267, 440, 000 Decimal Digits of π Calculation
We present efficient parallel algorithms for multiple-precision arithmetic operations of more than several million decimal digits on distributed-memory parallel computers. A parallel implementation of floating-point real FFT-based multiplication is used because a key operation in fast multiple-precision arithmetic is multiplication. We also parallelized an operation of releasing propagated carr...
