Program 5-6: Program of explicit type conversion from float to int.

Question

Accepted Answer

> [!TLDR]
> `int()` performs explicit float → int conversion by *truncating* the decimal part — `47.95` becomes `47`, never `48`.

**The idea (Explicit Type Conversion).** Going from `float` to `int` is a "narrowing" conversion: the fractional part cannot be represented in an integer, so it is **lost**. Because data is lost, Python never does this implicitly — the programmer must ask for it explicitly with `int()`. Knowing exactly *how* the fraction is removed (truncation toward zero, not rounding) is the whole point of this program.

**Program**

```python
# prog5-6.py
# Program of explicit type conversion from float to int
price = 47.95
priceInt = int(price)      # explicit float -> int
print(price)
print(priceInt)
print(type(priceInt))
print(int(-3.9))           # negative values truncate toward zero
```

**Expected output**

```
47.95
47
<class 'int'>
-3
```

**Key lines**

- `priceInt = int(price)` — the cast simply *drops* everything after the decimal point: 47.95 → 47. The original `price` still holds 47.95. …
