Digging a little deeper I found in the domain 'Integer':

(1) -> positiveRemainder(-13,10)

   (1)  7
                                                Type: PositiveInteger

I presume this is what you were looking for?

Also take a look at

(2) -> addmod(13,1,10)

   (2)  4
                                                 Type: PositiveInteger
(3) -> submod(13,1,10)

   (3)  12
                                                 Type: PositiveInteger
(4) -> mulmod(13,2,10)

   (4)  6
                                                 Type: PositiveInteger
