Question

In PowerShell, how can I test if a variable holds a numeric value?

Currently, I\'m trying to do it like this, but it always seems to return false.

Answer 1

If you want to check if a string has a numeric value, use this code:

$a = "44.4"
$b = "ad"
$rtn = ""
[double]::TryParse($a,[ref]$rtn)
[double]::TryParse($b,[ref]$rtn)
