The toString()
method returns a string representing the specified BigInt
object. The trailing "n" is not part of the string.

toString() toString(radix)
radix
Optional
Optional. An integer in the range 2 through 36 specifying the base to use for representing numeric values.
A string representing the specified BigInt
object.
RangeError
If toString()
is given a radix less than 2 or greater than 36, a RangeError
is thrown.
The BigInt
object overrides the toString()
method of the Object
object; it does not inherit Object.prototype.toString()
. For BigInt
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 the radix
is not specified, the preferred radix is assumed to be 10.
If the bigIntObj
is negative, the sign is preserved. This is the case even if the radix is 2; the string returned is the positive binary representation of the bigIntObj
preceded by a -
sign, not the two's complement of the bigIntObj
.
toString
17n.toString(); // '17' 66n.toString(2); // '1000010' 254n.toString(16); // 'fe' -10n.toString(2); // -1010' -0xffn.toString(2); // '-11111111'
BigInt
There is no negative-zero BigInt
as there are no negative zeros in integers. -0.0
is an IEEE floating-point concept that only appears in the JavaScript Number
type.
(-0n).toString(); // '0' BigInt(-0).toString(); // '0'
