PowerShell equality operator not a symmetric relation?

Question

Can someone please explain to me why the equality operator in PowerShell is not a symmetric relation??

PS> \"\" -eq 0
False
PS> 0 -eq \"\"
True
         


        

Answer 1

My first guess is that in the first case, there is a conversion of the right hand operand from 0 to "0" (the type of the left hand operator being a string), therefore "" is not equal to "0". In the second case, there is a conversion from "" to int, and "" is considered as being 0.

Try 3 + ""
