In Powershell what is the idiomatic way of converting a string to an int?

Question

The only method I have found is a direct cast:

> $numberAsString = \"10\"
> [int]$numberAsString
10

Is this the standard approach in

Answer 1

$source = "number35"

$number=$null

$result = foreach ($_ in $source.ToCharArray()){$digit="0123456789".IndexOf($\_,0);if($digit -ne -1){$number +=$\_}}[int32]$number

Just feed it digits and it wil convert to an Int32
