Set Theory

A branch of mathematics studying collections of objects, with operations like union, intersection, and complement.

Détail technique

Set Theory calculations are a source of common errors: a price increase from $100 to $150 is a 50% increase, but returning from $150 to $100 is a 33.3% decrease. Percentage points differ from percentages: an interest rate moving from 2% to 3% is a 1 percentage point increase but a 50% relative increase. In computing, floating-point arithmetic can introduce rounding errors — JavaScript's 0.1 + 0.2 = 0.30000000000000004. Use integer arithmetic (cents, basis points) for financial calculations.

Exemple

```
Set Theory calculation:

  Input:  value = 42
  Apply set theory: result = f(42)
  Output: result
```
