Manipulating numbers

Basic mathematical operations in PowerShell make use of the operators discussed in Chapter 4, Operators.

Formatting numbers was also introduced 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.

Large byte values

PowerShell provides operators for working with large byte counts. These operators are as follows:

• nKB: Kilobytes (n * 1024^1)
