Synopsis
numberObject.toString(radix)
Arguments
- radix
An integer between 2 and 36 specifying the base of the number system used to represent
numberObject
in string format. This argument is optional; if omitted, it defaults to 10.
Returns
The value of numberObject
converted to a
string.
Description
The toString( )
method retrieves the value of a
Number
object, converts that value to a string,
and returns that string. We may use the
radix
argument to convert numeric values
between different bases (e.g., binary, octal, decimal, and
hexadecimal). The letters A-Z are used to represent digits with the
value 10-35, respectively, although ordinarily only A through F are
used (to represent the hex digits equivalent to 10 through 15).
To use Number.toString( )
with a primitive
numeric value, surround the value with parentheses, as in:
(204).toString(16);
Example
x = new Number(255); trace(x.toString( )); // Displays: "255" (i.e., decimal) trace(x.toString(16)); // Displays: "ff" (i.e., hexadecimal) trace(x.toString(2)); // Displays: "11111111" (i.e., binary) // Convert a hex literal to decimal trace((0xFFFFFF).toString(10)); // Displays: "16777215"
