BigInt.parseInt ( string, radix )
|
|
|
|
The parseInt function produces a BigInt value dictated by
|
|
interpretation of the contents of the string argument according to
|
|
the specified radix.
|
|
|
|
The algorithm is the same as 18.2.5 but with the following edits:
|
|
|
|
* For all cases which result in returning NaN, throw a SyntaxError
|
|
exception.
|
|
* For all cases which result in returning -0, return 0n.
|
|
* Replace the second to last step, which casts mathInt to a Number,
|
|
with casting mathInt to a BigInt.

18.2.5 parseInt ( string, radix )

|
[...]
|
|
2. Let S be a newly created substring of inputString consisting of
|
|
the first code unit that is not a StrWhiteSpaceChar and all code
|
|
units following that code unit. (In other words, remove leading
|
|
white space.) If inputString does not contain any such code unit,
|
|
let S be the empty string.
|
|
[...]
|
|
11. If S contains a code unit that is not a radix-R digit, let Z be
|
|
the substring of S consisting of all code units before the first
|
|
such code unit; otherwise, let Z be S.
|
|
12. If Z is empty, return NaN.
