Powershell command to check if the data type of variable is integer, if it has characters it should respond with a message "Enter Only number"

[int]$name = Read-Host Enter the KB numberIf ($name -is [int]) {     wusa /uninstall /kb:$name    write-Host "This will uninstall windows update KB$name"} else {    write-Host "Enter only the number"}

Here in this PowerShell scripts, whenever a characters is typed is returns an error instead of message "Enter only the number".
