Is there a limit in Javascript to decimal places on big floats?

Question

I\'m facing the following issue/behavior:

console.log(1234567892012.123456);   // 1234567892012.1234
console.log(12345678920123.123456);  // 12345678920123.1         


        

Answer 1

Yes, you are seeing the inherent limitations of 64-bit floating point. If you really need more than two decimal places on a number as big as 123,456,789,201,234, you need some sort of extended arithmetic library. This question has some suggestions and discussion.
