Syntax
number.toString( [radix] )
Parameter
- radix
- An integer between 2 and 36 specifying the base to use for representing numeric values.
Description
The Number object overrides the toString method of the Object object; it does not inherit Object.toString. For Number objects, the toString method returns a string representation of the object in the specified radix.
The toString method parses its first argument, and attempts to return a string representation in the specified radix (base). For radixes above 10, the letters of the alphabet indicate numerals greater than 9. For example, for hexadecimal numbers (base 16), a through f are used.
If toString is given a radix not between 2 and 36, an exception is thrown.
If the radix is not specified, the preferred radix is assumed to be 10.
Examples
var count = 10; print(count.toString()); // displays "10" print((17).toString()); // displays "17" var x = 6; print(x.toString(2)); // displays "110" print((254).toString(16)); // displays "fe"
