Hi Mohammad,
this decision is up to you:
If you want provide the full PSUtilities Package to all your installations/instances or not?
In my project we provide the full package to all installation/instances as we are using several services out of it.
On the other side, if you only need this particular service, feel free to create a copy in one of your custom packages and use this copy in your code.
BTW:
When ever we are migrating to a newer version of IntegrationServer we check if there are appropriate services in WmPublic package available and replace the PSUtilities based services with those from WmPublic package.
Please note, that ps.util.math:modDivideInts is implemented as Java Service as most of the services in the PSUtilities package are Java Services.
Regards,
Holger
