Math on batch (win)

Question

I am developing a CMD batch. I want to do some math in it. This formula: (x+1)100:y

So in batch, x = %x%, and y = %y%. I know how to set t

Answer 1

The set command supports some limited calculation. In your case, you want: set /a result=(100*x)/y

Run set /? to see full documentation on what is supported. The /a switch does automatic variable substitution, so you can use x instead of %x%.
