Chapter 5. Fast Numbers
As it is a numerical programming language, fast computations with numbers are central to everything we do in Julia. In the previous chapters, we discussed how the Julia compiler and runtime perform across a wide range of code. In this chapter, we will take a detailed look at how these core constructs are designed and implemented in Julia.
In this chapter, we will cover the following topics:
- Numbers in Julia
- Trading performance for accuracy
- Subnormal numbers
Numbers in Julia
The basic number types in Julia are designed to closely follow the hardware on which it runs. The default numeric types are as close to the metal as possible—a design decision that contributes to Julia's C-like speed.
Integers
Integers in Julia are stored as ...
