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.
