BigDecimal(Variable Precision Floating Library for Ruby)

Japanese

BigDecimal is an extension library for the Ruby interpreter. Using BigDecimal class, you can obtain any number of significant digits in computation. For the details about Ruby see:

Introduction

Ruby already has builtin (variable length integer number) class Bignum. Using Bignum class,you can obtain any integer value in magnitude. But, variable length decimal number class is not yet built in. This is why I made variable length floating class BigDecimal. Feel free to send any comments or bug reports to me. shigeo@tinyforest.gr.jp I will try(but can't promise) to fix bugs reported.

Installation

The Ruby latest version can be downloaded from Official Ruby page. Once decompress the downloaded Ruby archive,follow the normal installation procedures according to the documents included.

Usage and methods

Suppose you already know Ruby programming, to create BigDecimal objects,the program would like:
   require 'bigdecimal'
   a=BigDecimal::new("0.123456789123456789")
   b=BigDecimal("123456.78912345678",40)
   c=a+b
