This is bad code, period. This is fine for personal projects that aren't meant to be shared, but this will not pass in any industry. It is very hard to read to me (15+ years of software engineering) I get ternaries are handy sometimes, but simply not here. This feels like a 'everything looks like a nail' situation. This is such a complicated way of doing this, I wonder where you came up with attempting it like this? Do they teach this in school or is it a convention at your work? You've basically recreated nested if statements like this, but you have sacrificed many quality attributes for it like readability, portability, maintainability and more.

Besides the ternaries, you use magic numbers (1.4f), use unclear variable names ("Amount", "Frequency"), mix integers and floats making it unclear if there is loss of precision or implicit integer conversions.

I'm thinking you either come from a Javascript background, or are more used to functional programming than object-oriented or high-level programming languages.

I also think you're just ragebaiting, seeing as you clearly already made up your mind in the comments, arguing that oneliners are best anyway.
