ECMA Section: 15.7.4.2.1 Number.prototype.toString()
Description:
If the radix is the number 10 or not supplied, then this number value is
given as an argument to the ToString operator; the resulting string value
is returned.
If the radix is supplied and is an integer from 2 to 36, but not 10, the
result is a string, the choice of which is implementation dependent.
The toString function is not generic; it generates a runtime error if its
this value is not a Number object. Therefore it cannot be transferred to
other kinds of objects for use as a method.
