As a case in point, the following attempt to assign a string to a variable which has been explicitly declared as Int32 fails: PS C:\Users\Administrator> $myvariable = 520 Any attempt to do so will result in an error message from the shell. Note that once the type has been explicitly set on a variable, it is not possible to implicitly change the variable type simply by assigning a value of a different type to the variable. PS C:\Users\Administrator> $myvalue.gettype() In the case of explicitly making a value Decimal, the value may be followed by the d character: PS C:\Users\Administrator> $myvalue = 10d For example: PS C:\Users\Administrator> $myval = 10
POWERSHELL CONVERT STRING TO BOOLEAN FULL
Rather than having the type implied, the type may be also be explicitly set by prefixing the value with either the full or short type name. This technique may also be used to identify which type will be used for a value by enclosing the actual numeric value in question in parentheses and then using the gettype() as previously outlined: PS C:\Users\Administrator> (9898.989).gettype().fullname Net type name use gettype().fullname as follows: PS C:\Users\Administrator> $myval.gettype().fullnameĪlternatively, the short name may similarly be obtained using gettype().name as illustrated below: PS C:\Users\Administrator> $myval.gettype().name
POWERSHELL CONVERT STRING TO BOOLEAN WINDOWS
PS C:\Users\Administrator> $myval.gettype()Īs illustrated in the above PowerShell console output, a variable assigned the value 10.432 is stored as type Double by Windows PowerShell. For example: PS C:\Users\Administrator> $myval = 10.432 It is possible to identify the type of a variable by using the gettype() method of the object. Similarly, if the number contains a fraction then a Decimal or Double type will be used. If, for example, the value is too high for an Int32 an Int64 may be created. Simple casting will not work, because Booleantrue and Boolean. When using a number, it is not usually necessary to prefix the value with the type since PowerShell is generally able to ascertain the correct type based on the size and format of the value. Boolean, you will have to convert that String variable to the Boolean type. inputs context is identical except that the inputs context preserves Boolean values as Booleans instead of converting them to strings.
