I'm working on a function in my PowerShell script that checks if two price points are within an acceptable range. The issue I'm having is with casting string parameters to float. Specifically, I have two parameters, `$p1` and `$p2`, both declared as strings. When I try to cast them to float, I notice that instead of getting the expected `System.Single` type, it retains `System.String`. I tested casting a string in the console directly, and it worked fine, so I'm wondering if there's something about the function structure that's causing this. Any ideas?

Have you considered using the `Parse()` method from the system? That might help with any tricky string format issues you have. You can do something like `$p1 = [system.double]::Parse($p1)` to ensure it converts correctly.
One thing I noticed is that you're using double quotes for your if checks, which can introduce issues with variable evaluation. Try switching to single quotes for matching literals or use backticks to escape the dollar sign. That could help fix your type casting issue as well.
You might be hitting a type conversion wall here. Instead of trying to change the original parameter types directly, it might be better to create new variables. For instance, using `$q1 = [float]$p1` would be a cleaner way to handle it without running into type issues.
That makes total sense! I’ll give that a try.
I think your problem might stem from the way you're checking for the dollar sign. Try using a switch to remove it, like `$p1 = $p1 -replace '$'` before casting to float. That could make the casting clearer for PowerShell.
It looks like you’re trying to cast the strings to float after they've already been defined as strings in the parameters. Once they're declared, PowerShell can get a bit tricky with types. A suggestion would be to try something like this: `$p1 = [float]$p1` after you clean up the dollar sign.
Thanks for the tip! I didn’t realize that would cause issues.
Got it, I'll modify that!
