Calculations on command prompt

[Verilog]

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.
