Number.MIN_SAFE_INTEGER — negative precision loss

📖 Usage Example

// Most negative safely representable integer
Number.MIN_SAFE_INTEGER   // → -9007199254740991
Number.MIN_SAFE_INTEGER - 1 === Number.MIN_SAFE_INTEGER - 2   // → true (unsafe!)

Use Number.MIN_SAFE_INTEGER as the lower bound when working with negative integers to avoid silent precision loss.

Precision Loss Below MIN_SAFE_INTEGER

Just like positive integers beyond MAX_SAFE_INTEGER, integers below MIN_SAFE_INTEGER lose precision.

💡 Hints (1)

• Precision loss is symmetric: it happens below `MIN_SAFE_INTEGER` just as it does above `MAX_SAFE_INTEGER`.
