Manipulating numbers

Basic mathematical operations in PowerShell make use of the operators discussed in Chapter 4, Operators.The following examples review the use of the format operator with numeric values:

'{0:x}' -f 24244      # Lower-case hexadecimal. Returns 5eb4
'{0:X}' -f 24244      # Upper-case hexadecimal. Returns 5EB4
'{0:P}' -f 0.28232    # Percentage. Returns 28.23%
'{0:N2}' -f 32583.122 # Culture specific number format.
                      # 2 decimal places.
                      # Returns 32,583.12 (in culture en-GB)

Format operations like those above return string values. Once a number has been formatted with the format operator, -f, it will no longer sort as a numeric value.PowerShell allows direct use of numbers written as hexadecimal.

Hexadecimal

Hexadecimal formats are easily accessible in PowerShell. PowerShell returns the decimal form of any given hexadecimal number when the hexadecimal value is prefixed with 0x:
