Behold the magnificent ReverseSign() function that single-handedly brought down an entire postal system! Instead of the elegant return -d , some genius decided to check if the number is negative, make it positive, and then... subtract it from itself and multiply by 2? That's like driving to the grocery store by first going to Mexico, then Canada, then back home. The real horror is that this cosmic abomination of code was responsible for financial calculations that sent innocent people to prison. Imagine having your life destroyed because someone couldn't grasp the concept of a negative sign. This is what happens when you let people who failed "Programming 101" write mission-critical financial software. Fun fact: This code is so bad that it fails for the number 0 (which doesn't change sign) and introduces potential overflow errors. It's like building a nuclear reactor with duct tape and wishful thinking.

When you need to reverse a number's sign but decide to take the scenic route through Absurdistan... This function is the programming equivalent of using a nuclear submarine to cross a puddle. The code checks if d is negative, then uses Abs() to make it positive (reasonable). But if it's positive? It subtracts d*2 from itself—a galaxy-brain approach to multiplication by -1. What makes this truly horrifying is that this overcomplicated monstrosity was part of the UK Post Office's Horizon system that led to the wrongful prosecution of hundreds of postal workers. Real people went to jail because someone couldn't write d = -d . The tragic irony? The comment literally shows the correct solution right above the function. It's like putting "just use stairs" in the elevator manual, then designing a catapult instead.
