Find and replace "." character

There are some folder. For example 0.8, 0.9, 1.0. Between the these name max number is 1.0. Actually ı can find value. But I want to write as "1.0" format to .txt file. 

$maxvalue = ($var | Measure -Max).Maximum
 $vers = 'v'+$maxvalue

find the max value in $var strings. When I want to bring 'v' character to this name it looks like v1. But I want to be like v1.0 for other file process in my code. How can protect this name with ".0" caracter and add text file. Thanks for your support

If in your current locale settings, you use the decimal point (.), this should do it:

$vers = 'v{0:F1}' -f $maxvalue

However, if (like it is for me), the current locale setting is e decimal comma (,), you need to either temporarily set the current culture to for instance 'en-US':

$oldCulture = [cultureinfo]::CurrentCulture
[cultureinfo]::CurrentCulture = 'en-US'
$vers = 'v{0:F1}' -f $maxvalue
[cultureinfo]::CurrentCulture = $oldCulture

Or do:

$vers = 'v' + $maxvalue.ToString("F1",[cultureinfo]::InvariantCulture)

Please also have a look at the excellent explanation by mklement0
