As you can see from the result, everything was widened to a double-precision floating point number. (Widening means converting to a representation that can handle larger or wider numbers: a [long] is wider than an [int], and so forth.) Now let s be a bit trickier. Let s put the floating point number into quotes this time. 56

The .NET single-precision floating point representation isn t typically used unless you request it. In PowerShell, there usually isn t a performance benefit for using single precision, so there is no reason to use this less precise representation.

Now let s look at some simple examples that involve only integers. As you would expect, all these operations result in integers as long as the result can be represented as an integer.

PS (8) > 6/3 2 PS (9) > (6/3).GetType().FullName System.Int32
Since 6 is divisible by 3, the result of this division is also an integer. But what happens if the divisor isn t a factor Let s try it and see.
PS (10) > 6/4 1.5 PS (11) > (6/4).GetType().FullName System.Double
The result is now a double. The system noticed that there would be a loss of information if the operation were performed with integers, so it s executed using doubles instead. Finally, let s try some examples using scientific notation. Let s add an integer to a large decimal.
PS (10) > 1e300 1E+300 PS (11) > 1e300 + 12 1E+300
The operation executed with the result being a double. In effect, adding an integer to a number of this magnitude means that the integer is ignored. This sort of loss is considered OK by the system. But there is another numeric type that is designed to be precise: System.Decimal. Normally you only use this type when you really care
TYPE MANAGEMENT IN THE WILD, WILD WEST
about the precision of the result. Let s try the previous example, adding a decimal instead of an integer.
PS (12) > 1e300 + 12d Cannot convert "1E+300" to "System.Decimal". Error: "Value was either too large or too small for a Decimal." At line:1 char:8 + 1e300 + <<<< 12d PS (13) >
This results in an error because when one of the operands involved is a [decimal] value, all operands are converted to decimal first and then the operation is performed. Since 1e300 is too large to be represented as a decimal, the operation will fail with an exception rather than lose precision. From these examples, you can see that while the PowerShell type conversion system is aggressive in the types of conversions it performs, it is also careful about how it does things. Now that you have a sense of the importance of types in PowerShell, let s look at how it all works. 3.1.2 The type system and type adaptation Since everything in PowerShell involves types in one way or another, it s important to understand how the PowerShell type system works. That s what we re going to cover in this section. At the core of the PowerShell type system is the .NET type system. Little by little, .NET is expanding to encapsulate everything in the Windows world, but it hasn t swallowed everything yet. There are still several other object representations that Windows users, especially Windows system administrators, have to deal with. There s COM (essentially the precursor to.NET); WMI, which uses MOF (Management Object Format) definitions; ADO database objects; ADSI directory services; and so on (welcome to Object Alphabet Soup). There s even everyone s favorite old/new (as in everything old is new again) object representation: XML. And finally the .NET libraries, as well-designed as they are, aren t always quite what you want them to be. In an effort to bring harmony to this object soup and fix some of the shortcomings of the various object representations, PowerShell uses a type-adaptation system that masks all of the details of these different objects representations. A PowerShell script never directly accesses an object. It always goes through the type adaptation layer the PSObject layer that rationalizes the interfaces presented to the user. The PSObject layer allows for a uniquely consistent user experience when working with the different types of objects. This architecture is shown in figure 3.1. When you see an expression like
