Powershell script strange behavior

I'm experiencing strange behavior with a simple powershell script.

$number = read-host "enter 50"
$guess = read-host "enter 100"

if ($guess -lt $number){
write-host "$guess is less than $number"}
else{
write-host "$guess is greater than $number"}

This script should go to the else statement when entering in 50 and 100 as directed but it doesn't and I can't figure out why. Any input would be much appreciated.

On a side note. After running the script I can in type in powershell
$guess -lt $number and get false which is as expected.

because that is considered as [string]
if you place

[int]$number = read-host "enter 50"
[int]$guess = read-host "enter 100"

if ($guess -lt $number){
write-host "$guess is less than $number"}
else{
write-host "$guess is greater than $number"}

That's not true, as the result is still $true when using the read-host results. However, if you assign numeric literals 50 and 100, the condition is $false now.

You're right Qlemo in my powershell session I had previously assigned the INT's to the variables in order to get the false result. After restarting my session it displayed the incorrect result. The irony is the book I'm reading on powershell has this script in it as a working model. Someone needs to fire the author and editor.
