In JavaScript I would like to create the binary hash of a large boolean array (54 elements) with the following method: function bhash(arr) { for (var i = 0, L = arr.length, sum = 0; i < L; sum += Math.pow(2,i)*arr[i++]); return sum; }...

I'm working on the Project Euler problems (currently question 13). For this question I have to find the first 10 digits of the sum of 100 numbers all of a size similar to this: 91,942,213,363,574,161,572,522,430,563,301,811,072,406,154,908,25...

I need to convert a string to BigInt like BigInteger in Javascript Example var reqId = "78099864177253771992779766288266836166272662"; var result = parseInt(reqId); document.write(result); Resultant value not matching since JavaScript onl...

How to from a JavaScript String, assuming that it will be converted to base 2 number representation, get length of it? var a = "272536128346512928170680631080519528229146964434271410085551421233166821449322540716328336885932620456894930082416553...

I'm currently making my own BigInt class, by splitting numbers by 7 digits. (i.e. in base 10,000,000) I implemented addition, subtraction, and multiplication, and now I'm implementing division and mod. I wrote a code that performs division b...

I'm trying to implement a BigInt type in JavaScript using an array of integers. For now each one has an upper-bound of 256. I've finished implementing all integer operations, but I can't figure out how to convert the BigInt to its string...

In Java, I can get a BigInteger from a String like this: public static void main(String[] args) { String input = "banana"; byte[] bytes = input.getBytes(StandardCharsets.UTF_8); BigInteger bigInteger = new BigInteger(bytes);...

I hope I'm overthinking this and there's an obvious solution. From the API (GET statuses/user_timeline) max_id - Returns results with an ID less than (that is, older than) or equal to the specified ID. "or equal to" means it wi...

I thought the max integer value for javascript was 2^53, but when I do the following: parseInt(Math.pow(2, 53)) + 10 I correctly get 9007199254741002 (= 9007199254740992 + 10) Why is that? I want to use a bigint.js library only if the number...
