Formatting number question

I have this PS script that gives me back the top 5 processes consuming the most virt memory. I'd like to display the MB with not so many numbers to the right of the decimal point.

Scripts
*****
#Top 5 PROCESSES CONSUMING THE MOST VIRT MEMORY
write-host `n  "Top 5 PROCESSES CONSUMING THE MOST VIRT MEMORY (MB)" -BackgroundColor Blue -ForegroundColor White
Get-Process -ComputerName $Server |Select Name,@{n="VM";e={$_.VM /1MB}} | Sort-Object VM -Descending | Select-Object Name, VM -First 5 | Format-Table –AutoSize


Output
******
 Top 5 PROCESSES CONSUMING THE MOST VIRT MEMORY (MB)

Name                            VM
----                            --
ThermalController       770.83203125
svchost                      744.21875
mbamservice               603.19140625
AWCCServiceController 599.30078125
powershell                   582.765625


Desired Output
************

 Top 5 PROCESSES CONSUMING THE MOST VIRT MEMORY (MB)

Name                            VM
----                            --
ThermalController        770.83
svchost                      744.21
mbamservice              603.19
AWCCServiceController 599.30
powershell                   582.76


I know that there's a way to format the numbers via this method: http://technet.microsoft.com/en-us/library/ee692795.aspx
but I don't know how to plug it in the script properly without generating an error.
