Summary: Learn how to use Windows PowerShell to round numbers.
Is there an easy way to use Windows PowerShell to round numbers up or down in a computation that produces a large amount of numbers after the decimal point?
Use the static Round method from the [math] class:
PS C:\> $a = 22/7
PS C:\> $a
PS C:\> [math]::Round($a)
What about rounding to a limited number of decimal places? As in financial calculations where 2 places are standard?
Found it.......... [math]::Round($a, 2)
:) Other way [math]::Round(22/7) - When we are feeding inputs
$a = 22; $b = 7; [math]::Round($a/$b) - When are not sure about the value A and B
$var = Get-Random -Maximum 10.5 -Minimum 1.1
'Original Value is: ' + $var
'Rounded Value is: ' + [math]::Round($var)
PowerShell Rocks :)
[math]::Truncate(22/7) does the same job :)
Please ignore truncate method it' just omitting the values after decimal not rounding up the values. My bad. Sorry !!!
[math]::Floor() and [math]::ceiling() are also useful for rounding down and up, respectively, to the integer.
Very useful. I have used this several times!
