If it is stored in another unit for example DatabaseSize Property is in MB then you can multiply it by the unit of measure and divide by GB.

Math with variables powershell. PowerShell can already do math pretty easily so well do some basic addition. A practical example of rounding. To display the value of a variable simply enter the variable.

PS C pi mathpi PS C r 2 PS C 2 pi r 12. In addition to standard PowerShell methods we can also call Net Math functions. Notice that here the decimal 25 rounded down to 2.

But well save that for another day. Variables and Operators add subtract divide In PowerShell all PowerShell can also assign values to multiple variables. A 0 b 12 c -1-2 ba ca In this example the expression a is evaluated before b a.

Whenever you put a number in a variable it automatically becomes an integer variable. PS C mathpi 3. Windows PowerShell SystemMathStatic Method.

A variable is a unit of memory in which values are stored. MathRound var p Round a variable to p places. Instead of adding all of the sides we will multiple the length and width of the rectangle to get the area.

Such as assigning the value directly to a variable or using the format operator. PS C x 1000. A variable in PowerShell begins with dollar sign and its name can contain any letters numbers and underscores.

PS C x 10 20. PS C y x 500. ForEachnumber in value newNumbers MathPownumber - avgCountAverage 2 The above code takes each number in the array get the number minus the average to the power of 2 and then adds it to the variable newNumbers.

You can do exactly the same thing using Windows PowerShell. PS C mathRound225 1 22. The key is the index and the value is what was returned as the match Since there is only one value in the Matches variable you can get to the value of the match by referencing the key-pair by its.

This is shown here where I get the circumference of a circle that has a radius of 2. However there are cases where this does not always work as expected. File sizes in Windows PowerShell appear as bytes.

PowerShell has no built-in mechanism for enforcing variable types for example string variables can begin with letters or numbers. MyVariable Some String Value. Yay mathIf we try using that within a string however it ends up printing it instead of evaluating it.

So for MB unit. In the following example the 35 rounds up because the number 3 is odd. MathRound var mathAbs n mathBigMul mathCeiling n Rounds everything up towards positive infinity.

Creating a new variable can be done in several ways. Area of a Rectangle Length 10 Width 5 Result Length Width pscustomobject Length Length Width Width Perimeter Result. VarX varY 64 varA The following example shows a complicated assignment statement.

The hashtable a key-pair has a key and a value. To assign a value to a variable we use the operator. In general PowerShell is able to detect when a mathematical operation is being performed and convert strings on the fly to permit this.

There are no separate math functions in PowerShell. Yet numeric variables can also begin with letters or numbers. If you have ever wondered about the PowerShell double colon then all is revealed it means a static method.

PowerShell converts numbers to integers You can then apply the basic math operations with the same syntax you learned in school. I then finish the calculation and store it in the variable stdDev. MathDivRem mathEquals nm Compare two values and return a boolean truefalse result.

So when you need to access a maths function such as Round or Sqrt just call for the SystemMath. Variables and Operators add subtract divide In PowerShell all variable names start with the character. However you can restrict the values a PowerShell variable accepts by preceding it with int or string here is an example.

To see this in action.
