Working with Basic Haskell Types
The names of types in Haskell always start with a capital letter, for example, Integer, not integer. You’ll learn about several different built-in types throughout this chapter, but to get started let’s take a look at a few of the most common types:
-
Integer: A signed integer value. It’s unbounded, meaning it can be arbitrarily large. Integer literals are written as numbers, as in 1234 or -1234.
-
Int: A signed integer value. Its size (32-bit or 64-bit) depends on your platform. Int literals are written as numbers, as in 1234 or -1234.
-
Word: An unsigned integer value. It’s the same size as an Int. Word literals are written as numbers, as in 1234.
-
Float: A single-precision IEEE floating-point value. Float literals ...
