yes, that is a big step backward. One of the details that people don't realize is that the Ada code probably had runtime checks inserted by the compiler to help catch issues. In addition, the Ada code most likely restricted the set of input values or prevented accidental mixing of different numerical values using its strong type system. When you convert to C, you lose all of that. If there is a code change down the road, you could have an error occur that might have been caught by the Ada compiler at compile time, or if not then by an Ada runtime check. Yes, testing has to be really good to minimize these cases, but we all know it's difficult and very time consuming to develop test for every possible combination. In addition, when you have to do code reviews, you have to worry about a much wider range of possible bad values that can be passed around which can screw up the results.
