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

You can check whether the variable is a number like this: $val -is [int]

This will work for numeric values, but not if the number is wrapped in quotes:

1 -is [int]
True
"1" -is [int]
False
