Powershell - Round down to nearest whole number

Question

What\'s the best way to round down to nearest whole number in Powershell?

I am trying [math]::truncate but its not giving me predictable results.

Example:

<

Answer 1

Ah, I see. Looks like the datatype needs to be decimal:

[decimal] $de = 17.2/.1
[double] $db = 17.2/.1

[math]::floor($de)
172
[math]::floor($db)
171
