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

[Math]::floor($x) is the built-in way to do it.

Just be aware of how it will behave with negative numbers. [Math]::floor(5.5) returns 5, but [Math]::floor(-5.5) returns -6.

If you need the function to return the value closest to zero, you'll need:

If ($x -ge 0) {
    [Math]::Floor($x)
} Else {
    [Math]::Ceiling($x)
}
