Digital filters that can handle fixed point inputs (with different word sizes), floating point inputs, as well as arrays is another example of reuseable code. The 3x cost has to deal with not just writing the code but testing it (all the various paths in different applications). You can't just write code, have a code review, and then test in one application and magically call it "reuseable". To test reuseability to have to test the code's ability to be reused. Code that just can be used in the same application, with just minor updates is not what is known as reuseable in the software industry. Although some refer to it as vertically reuseable as opposed to horitizally reuseable, but that is just to satisfy naive managers.
