Ironically, the worst thing I ever saw a coworker do was to change a function that accepted an Integer value between 0 and 32767 to one that accepted a Float between 0.0 and 1.0. Perfectly sensible change except that it resulted in a 120 mph knuckleball fired a foot above a 10 year old kid’s head, followed by a fist fight between the client and my boss.
Oldman.setHealth(0.0); //it is subunitary, but undefined behavior - will it access the ‘numeric value’ overload, or the ‘subunitary numeric value’ overload?
The high level setter function should be made to handle both string and numeric values.
If it contains “%” it’s a percentage value.
If it’s a string without a “%” it’s an absolute value and needs to be normalized.
If it’s a numeric value, it’s an absolute value.
If it’s a numeric 100, it’s 100%.
If it’s a subunitary numeric value, it’s a percentage.
yeah I’m gonna go ahead and reject your PR, please change this function to accept a decimal value between 0 and 1

That sounds like something that should have been caught by QA, integration tests or unit tests long before it was launching balls at ten year olds.
Yes, testing the new Little League control module on a field full of Little Leaguers was not the best plan.
What is a little league control module?
You push a button and it makes Little Leaguers do whatever you tell them to do. Very potent, should never be misused.
yeah every engineer knows you gotta set KidHeadKnuckleballClearance waaay higher than that, it’s compsci 101
absolute lunacy
Absolute (cm)
adding one
0:100%, automatically changes unit to %
(Word table properties)
"5%1 "
Oldman.setHealth(“dicktits”); //normalize pls
Oldman.setHealth(“-100±1%”); //make percentage pls
Oldman.setHealth(0.0); //it is subunitary, but undefined behavior - will it access the ‘numeric value’ overload, or the ‘subunitary numeric value’ overload?
Don’t write your own code just yet.
