You should convert using the current locale. Replacing , with . isn't reliable and is slightly slower (because another string must be created). Both Parse and TryParse have a culture parameter that you can use

PS D:\> $string = "2,55"
PS D:\> $culture = Get-Culture
PS D:\> [decimal]::Parse($string, $culture)
2.55
PS D:\> [decimal]$dec = 0
PS D:\> [decimal]::TryParse($string, [Globalization.NumberStyles]::Float, $culture, [ref]$dec)
True
PS D:\> $dec
2.55

If you know the locale of the input then parse directly in that locale by using GetCultureInfo

$culture = [cultureinfo]::GetCultureInfo('fr-FR')

Note that if the string contains the exponent like "2,55e2" then none of the current other answers actually work (although it may appear to work). For more details read How can I convert a string such as 5.7303333333e+02 to decimal in PowerShell?

Another way of converting this (not necessarily better) is using the ToDecimal method with a specific culture. Here I'm using the standard french culture.

 [System.Convert]::ToDecimal("2,55",[cultureinfo]::GetCultureInfo('fr-FR'))
 2.55

To force a conversion to a specific datatype, prefix the value or variable with the type in square brackets, this is known as a Cast Operator and forces the chosen datatype:

$string = "100.5"
$decimal = [decimal]$string

$string + 0.5
# Outputs 100.10.5

$decimal + 0.5
# Outputs 101,0

In short - 

[decimal]$string.Replace(",", ".")
