How do I take the integer value of a number?

• Using Type casting

There are 2 ways to cast PowerShell, one is a direct type cast, and the other is a conversion via the-as operator

2. PS f:\> [int] (3/2) # Direct Type casts
4. 2
6. PS f:\> (3/2)-as [int] #-as operator for type conversion
8. 2
10. PS f:\>

The result of the cast is rounded.

• Use , NET class

Now we need to find another way to solve the problem: Take "Max integer" with "not greater than value"

Use ". NET class, the "floor method" in the "math class" can be implemented

1. PS f:\> [Math]::floor (3/2)

1. 1

However, this method is only valid for positive numbers. If it is a negative number, use [math]::ceiling ] to take the smallest integer not less than the value of the parameter.

1. PS f:\> [Math]::ceiling ( -3/2)
2. -1

$size = ("{0:n2}"-F ($subFolderItems. SUM/1GB)) Keep two digits after the decimal point

$size =[math]::truncate ($disk. SIZE/1GB) to intercept the decimal point, preserving the integer

$size = ("{0:n2}"-F ($subFolderItems. SUM/1GB)) Keep two digits after the decimal point

$size =[math]::truncate ($disk. SIZE/1GB) to intercept the decimal point, preserving the integer
