You can cast any kind of object in PowerShell. Casting objects completely alters their attributes, enabling you to conduct a variety of operations on them. PowerShell now has the ability to add them together since we cast $string to an integer or utilize PowerShell to “convert” the string to an int. Let’s try adding the two numbers together once again. To do so, we utilize the cast operator in PowerShell to explicitly convert the text to an integer type. To get PowerShell to add the two numbers, we must first convert $string to an int and then inform PowerShell that $string is a number. Instead, it concatenated the two together, thereby combining them. PowerShell didn’t add the two numbers together since $string is simply string data.
