Numerical Types

Go

As we saw, Go provides a few different types to represent numbers.

These types include

uint which is used to store unsigned integers (those with values >=0) int used to storage signed integers (those which can be negative numbers) float64 used to store numbers with floating points (decimal places)

Because each type has it's own strengths and weakness, as well as constraints, then it's typical to use them for different purposes. Using a uint for everything is generally a bad idea.

In this challenge, there are a number of different variables already defined. The purpose of each of these values has been given as a comment above the variable definition.

Your goal is to choose which type you think best suits each variable given the description in the comment above it. Do not worry about which size to choose, instead choose either an int, a uint or a float64 depending on which one makes sense.

For redundancy here are the variables and their purpose.

var age = Used to represent a persons age in years
var balance = Used to represent a persons bank balance in the lowest denominator (pennies)
var radius = Used to store the radius of a circle.
var wordCount = Used to keep track of the number of words on a page
var executionTime = The amount of time some code took to execute, with 1's representing seconds.
