That's good because it's better to catch such errors at compile time instead of having your program crash. Notice that floor now returns an Integer value, which is what we want. Integer, which are arbitrary-precision integers, often called "bignum" or "big-integers" in other languages, and 2. Each floor includes a kitchen, lounge, and study area. -- Assuming that a number is not a prime if he is divisible by any number between 2 and his sqrt Wilson's theorem. Input: round 3.4 Output: 3 Input: 6 `div` 2 Output: 3 Example 2. In practice, its range can be much larger: on the x86-64 version of Glasgow Haskell Compiler, it can store any signed 64-bit integer. sumU . and y; for example gcd (-3) 6 = 3, gcd (-3) (-6) = 3, A floating literal stands for an application of fromRational Everything in Haskell has a type, so the compiler can reason quite a lot about your program before compiling it. pi, exp, log, sin, cos, sinh, cosh, Haskell also incorporates polymorphic types---types that areuniversally quantified in some way over all types.
