LessEqual

Function passes if new value is less than or equal to existing value

Greater

Function passes if new value is greater than existing value

NotEqual

Function passes if new value is not equal to existing value

GreaterEqual

Function passes if new value is greater than or equal to existing value

Always

Function always passes
