-- Filename: ratpack.vhd |
-- Purpose : Rational arithmetic package |
-- Author : Nikolaos Kavvadias <nikolaos.kavvadias@gmail.com> |
-- Date : 14-May-2010 |
-- Date : 17-Nov-2010 |
-- Version : 0.1 |
-- Revision: 0.0.0 (2009/07/25) |
-- Initial version. Added the definition of a rational number, and the |
13,6 → 13,8
-- Added: numerator, denominator, abs, relational operators (>, <, >=, |
-- <=, =, /=, changed the int2rat to to_rational, new version of |
-- int2rat (casting an integer to a rational). |
-- 0.0.2 (2010/11/17) |
-- Added an iterative version for the gcd computation (gcditer). |
