Integer and floating-point types in PowerShell - Mini Project: Build & Apply

Integer and Floating-Point Types in PowerShell

📖 Scenario: You are working with numbers in a PowerShell script. Some numbers are whole numbers, and some have decimals. You want to understand how to create and use both integer and floating-point numbers.

🎯 Goal: Learn how to create integer and floating-point variables in PowerShell, and display their values and types.

📋 What You'll Learn

Create an integer variable with a specific value

Create a floating-point variable with a specific value

Display both variables and their types

💡 Why This Matters

🌍 Real World

Scripts often need to work with different kinds of numbers, like counts or measurements with decimals.

💼 Career

Understanding number types helps in writing scripts that handle data correctly in automation tasks.

1

Create an integer variable

Create a variable called wholeNumber and set it to the integer value 42.

PowerShell

# Create a variable called wholeNumber and set it to 42
# Your code here

Need a hint?

Use = to assign the value 42 to the variable $wholeNumber.

2

Create a floating-point variable

Create a variable called decimalNumber and set it to the floating-point value 3.14.

PowerShell

$wholeNumber = 42
# Create a variable called decimalNumber and set it to 3.14
# Your code here

Need a hint?

Use = to assign the value 3.14 to the variable $decimalNumber.

3

Display the variables and their types

Use Write-Output to display the value of $wholeNumber and its type using GetType().Name. Then do the same for $decimalNumber.

PowerShell

$wholeNumber = 42
$decimalNumber = 3.14
# Display the value and type of wholeNumber and decimalNumber
# Your code here

Need a hint?

Use Write-Output with double quotes and $() to show the value and type.

4

Run the script to see the output

Run the script to display the values and types of $wholeNumber and $decimalNumber.

PowerShell

$wholeNumber = 42
$decimalNumber = 3.14
Write-Output "wholeNumber: $wholeNumber, Type: $($wholeNumber.GetType().Name)"
Write-Output "decimalNumber: $decimalNumber, Type: $($decimalNumber.GetType().Name)"
# Run the script to see the output

Need a hint?

Run the script in PowerShell. You should see the values and their types printed.
