-: Calculations On Command Prompt :- The command processor CMD.EXE comes with a mini-calculator that can perform simple arithmetic on 32-bit signed integers: C:\>set /a 2+2 4 C:\>set /a 2*(9/2) 8 C:\>set /a (2*9)/2 9 C:\>set /a "31>>2" 7 Note that we had to quote the shift operator since it would otherwise be misinterpreted as a "redirect stdout and append" operator. For more information, type set /? at the command prompt.
