1. ⚡️ Speed up percentage() by 40% …

   #### Why these changes?
   We initially refactored the code to opt for a more modern and efficient way of string formatting using f-strings.
   Then, we combined this with lazy evaluation to remove unnecessary computations.
   In the final stages, we micro-optimized by introducing constant pre-calculation and single-line conditionals.
   
   #### Correctness
   The better micro-optimized code maintains the same functionality as the original code.
   - Checks if the value is None and returns "-" if it is.
   - Multiplies the value by 100 and formats it as a percentage with the specified number of decimal places if the value is not None.
   Thus, it produces the same outputs for the same inputs and has the same side effects.
   
   #### How is this faster?
   The use of f-strings improves string formatting speed.
   Lazy evaluation immediately returns for None values, avoiding unnecessary calculations.
   Removing repeated computations (e.g., pre-calculating constant multipliers) reduces the computational overhead.
   Single-line conditionals make the execution path shorter and more efficient.
