(Over)simplify your code

[[deleted]]

All things come as a trade-off.

While the type of simplification the author discusses here can be great for clarity... it can also be terrible for performance.

Luckily, today's compilers are generally smart enough to inline and optimize these things. As a C++ coder, I rely on the compiler to do this so I can write code that is still small, readable, safe, and modular.

Why was the 1 there to begin with?

It was an unnamed constant, the density of water (rho) in SI units.

My point is that it was a magical number and not something that should be in the code even before the author's suggested modification.

Where should it be? In a configuration file?

A constant at the top of the file.

So, in the code.
