toFixed() — safe rounding example

📖 Usage Example

// Format number with fixed decimal places
(3.14159).toFixed(2)   // → '3.14'
(1.5).toFixed(0)       // → '2'
(100).toFixed(2)       // → '100.00'

Use toFixed() to format a number as a string with a specific number of decimal places, commonly used for monetary values.

toFixed() — Reliable Rounding

(1.25).toFixed(1) reliably returns '1.3'.

💡 Hints (1)

• Some values (like `1.005`) are tricky due to floating-point representation; prefer values like `1.25`.
