Who uses Calc?
Because of the way Calc is distributed it is difficult to obtain precise numbers of users. On a typical day, between one and two thousand users download Calc from our web site. Calc can also be obtained from magazine cover disks, online software archives, user’s home pages and in software collection CD’s sold separately or included with textbooks. We currently estimate that about 4 million users have downloaded Calc. Many users report that they have distributed the software around their departments or organizations, which include major industrial corporations and government departments. A large proportion of users are located in North America, although there are registered users in most countries of the world. As well as scientific and engineering industries, Calc is very popular in education, financial services and health-care. For further background you can see a selection of user comments.
