[removed] Bitwise shift of long long number

Question

I need to bitwise shift a value 64 times in JavaScript. But JavaScript starts rounding after 32.

For example:

for(var j = 0; j < 64;          


        

Answer 1

JavaScript stores all its numbers as 64 bit initally, but as soon as you start using bitwise operators the interpreter converts the number to a 32 bit representation..

Bitwise operators are a bit hacky in JS and so annoyingly you will probably have to do something a bit more clever, like write your own 64 bit functions.
