The math Package

Explore how to use Go’s math package to perform common mathematical operations and work with built-in constants. Understand functions like Abs, Sqrt, Pow, and Round, and learn how Go handles floating-point values such as NaN and Infinity. This lesson equips you with essential skills to perform accurate and efficient numerical computations in Go.

We'll cover the following...

Overview

The math package provides basic mathematical constants and functions for floating-point arithmetic (specifically float64). It defines commonly used constants:

  • math.Pi → π (3.141592653589793)

  • math.E → Euler’s number

  • math.Sqrt2

  • math.Ln2, math.Ln10

  • math.MaxFloat64, math.SmallestNonzeroFloat64 ...
