Describe the changes you've made:

This contribution adds a vulnerability that exploits solidity integer division which causes fractional loss due to truncation. I think we can create a new category called Solidity Math Issues which includes all the issues involving solidity math like divide by zero, rounding errors, rounding to 0, loss of precision, solidity truncation, etc in a single listing.
