Combination — Thuật ngữ

A selection of elements without regard to order — n choose r equals n!/[r!(n-r)!].

Chi tiết kỹ thuật

Combination is applied in computing through numerical algorithms that balance precision, performance, and memory. JavaScript uses 64-bit IEEE 754 floating-point for all numbers, providing ~15-17 significant decimal digits. For exact arithmetic (financial, cryptographic), BigInt or fixed-point libraries are required. Browser-based calculators implement combination using the same floating-point engine, making awareness of precision limitations important for correct results.

Ví dụ

```
Combination calculation:

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