Binary-coded decimal Binary-coded decimal In computing and electronic systems, binary-coded decimal (BCD) is a class of binary encodings of decimal numbers where each decimal digit is represented by a fixed number of bits, usually four or eight. Special bit patterns are sometimes used for a sign or for other indications (e.g., error or overflow). In byte-oriented systems (i.e. most modern computers), the term "unpacked" BCD usually implies a full byte for each digit (often including a sign), whereas "packed" BCD typically encodes two decimal digits within a single byte by taking advantage of the fact that four bits are enough to represent
Women in computing in Canada Women in computing in Canada Canada shares many of the concerns particularly prevalent in the developed and developing world about the current and future roles of women in computing, especially as these occupations increase in importance. As in much of the world where computing and information technology is a large industry, women have historically faced underrepresentation in education and industry. As a result, some Canadian women pursuing careers in these fields have had a lack of role models and faced sexism. There are many institutions and initiatives in Canada, however, which seek to increase representation for women in computing fields,
