Computer scientists write algorithms for a variety of problems. Some types of computation, such as representation of knowledge, use symbols and lists. Others, such as the construction of Web pages, may involve the manipulation of strings (sequences of alphabetic characters). Even when working with text, a significant amount of computation involves numbers. And, even though numbers seem simple, it turns out that there are some subtleties to the representation of numbers in Scheme. As you may recall from our first discussion of data types, when learning about data types, you should consider the name of teach type, its purpose, how Scamper displays values in the type, how you express those values, and what operations are available for those values. While it seems like “numbers” is an obvious name for this type, Scheme provides multiple kinds of numeric values. In each case, the purpose is the same: to support computation that involves numbers. As you probably learned in secondary school,

CSC 151 - Numeric values Numeric values Due Monday, 8 September 2025 --> Summary We examine a variety of issues pertaining to numeric values in Scheme, including the types of numbers that Scheme supports and some common numeric functions. Introduction Computer scientists write algorithms for a variety of problems. Some types of computation, such as representation of knowledge, use symbols and lists. Others, such as the construction of Web pages, may involve the manipulation of strings (sequences of alphabetic characters). Even when working with text, a significant amount of computation involve
