Check if value falls within a specific range powershell - powershell

Question

I am having a code which is giving me 2 values like below
$pattern = '\s(-?\d+.?\d+)\s'
$RX_Val = [regex]::Matches($RXTX_Data[0], $pattern).Value
$TX_Val = [regex]::Matches($RXTX_Data[1], $pattern).Value
PS C:\Windows\system32> $RX_Val
-3.4
PS C:\Windows\system32> $TX_Val
-2.3
Need get RX and TX value should fall under range -1 to -7
like the above 2 values falls within the range
if the values are like 1 and -8 respecively, then it should give error
I tried below code, but not getting the proper response
if((($RX_Val -gt -1) -and ($RX_Val -lt -7)))# -and (($TX_Val -gt '-1') -and ($TX_Val -lt '-7')))
{
Write-Host "OK"
}
else
{
Write-Host "NOT OK"
}
also tried
$RX_Val -In -1..-7
please let me know what i am missing here
Tried given solution in below way
$RX_Val = [int][regex]::Matches($RXTX_Data[0], $pattern).Value
$TX_Val = [int][regex]::Matches($RXTX_Data[1], $pattern).Value
if(($RX_Val -in -1..-7) -and ($TX_Val -in -1..-7))
{
Write-Host "OK"
}
else
{
$RXTX_Data | Out-File -FilePath "E:\$file_name" -Force
}
but failed for below scenario as the values are converted to int. it is suppose to print OK
$RX_Val=-0.1
$TX_Val=-1.5

The issue is that the value return by your regex extraction is a STRING. You need to convert it to an INT to be able to do your calculation.
$RX_Val = [int][regex]::Matches($RX, $pattern).Value
$TX_Val = [int][regex]::Matches($TX, $pattern).Value
Sure you can make the logic work from there.
As a bonus, the cast to [int] will also take care of the whitespace left from the regex.
