toFixed() — return type is string

📖 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() Returns a String

The result is always a string, even when the number looks like an integer.

💡 Hints (1)

• `toFixed` returns a string; use `parseFloat` if you need the numeric value back.
