Fix huge numbers in an idle game that show as 1e+21, NaN or 1000K

Once the counter grows big, the screen fills with ugly scientific notation, a word that is not a number, or a number that is rounded one step too high. This entry shows how to make the AI write a short display helper that stays readable and never lies at the edge.

Why this works

A big number on screen is only a message to a human, and it has to be short and true at the same time. The danger sits at the seams, where one unit of size turns into the next. Rounding first and then choosing the unit keeps the text honest.

When not to use it

Short text is wrong when the player needs the exact amount, such as paying a price or comparing two nearly equal offers. Show the full number there, with separators between the digit groups, and shorten only the headline counter.
