When comparing numbers, each of the operators -ge (greater than or equal to), -gt (greater than), -le (less than or equal to), and -lt (less than) are simple to use:

1 -ge 1        # Returns true 
2 -gt 1        # Returns true 
1.4 -lt 1.9    # Returns true 
1.1 -le 1.1    # Returns true 

String comparison with operators follows the generalized pattern 0123456789aAbBcCdD... rather than basing on a character table (such as ASCII):

• Cultural variants of characters, for example, the character å, fall between A and b in the list
• Other alphabets, for example Cyrillic or Greek, come after the Roman alphabet (after Z)

Comparison can be culture sensitive when using commands such as Sort-Object with the Culture parameter, but comparisons are always based on en-US when using the operators:

'apples' -lt 'pears'    # Returns true 
'Apples' -lt 'pears'    # Returns true 
'bears' -gt 'Apples'    # Returns true 

Or when using case-sensitive comparison:

'bears' -gt 'Bears'    # False, they are equal to one another 
'bears' -clt 'Bears'   # True, b before B
