F# for Quantitative Finance

By: Johan Astborg

Overview of this book

F# is a functional programming language that allows you to write simple code for complex problems. Currently, it is most commonly used in the financial sector. Quantitative finance makes heavy use of mathematics to model various parts of finance in the real world. If you are interested in using F# for your day-to-day work or research in quantitative finance, this book is a must-have.This book will cover everything you need to know about using functional programming for quantitative finance. Using a functional programming language will enable you to concentrate more on the problem itself rather than implementation details. Tutorials and snippets are summarized into an automated trading system throughout the book.This book will introduce you to F#, using Visual Studio, and provide examples with functional programming and finance combined. The book also covers topics such as downloading, visualizing and calculating statistics from data. F# is a first class programming language for the financial domain.

Understanding the number representation


In this section, we will show you how numbers are represented as integers or floating-point numbers in computers. Numbers form the foundation of computers and programming. Everything in a computer is represented by the binary numbers, ones and zeroes. Today, we have 64-bit computers that enable us to have a 64-bit representation of integers and floating-point numbers naively in the CPU. Let's take a deeper look at how integers and floating-point numbers are represented in the following two sections.

Integers

When we talk about integers, denoted as Z, we are talking specifically about machine-precision integers that are represented exactly in the computer with a sequence of bits. Also, an integer is a number that can be written without a fractional or decimal component and is denoted as Z by convention. For example, 0 is represented as 000000..., 1 is represented as ...000001, 2 is represented as ...000010, and so on. As you can see from this pattern...
