toString() — hex with radix 16

📖 Usage Example

// Convert number to string in a given base
(255).toString(16)   // → 'ff'
(255).toString(2)    // → '11111111'
(255).toString(10)   // → '255'

Use toString() with a radix argument to convert a number to its binary, octal, hexadecimal, or other base string representation.

Number.prototype.toString()

num.toString(radix?) converts a number to a string, with an optional radix (base).

(255).toString(16)  // → 'ff'
