As per the standard ES implements numbers as IEEE754 doubles. And per https://www.binaryconvert.com/result_double.html?decimal=053055050054055049056048053048053054056053048051050057054 and other programming languages https://play.golang.org/p/5QyT7iPHNim it looks like the 5726718050568503296 value can be represented exactly without losing precision. Why it loses 3 significant digits in JS (reproduced in latest stable google chrome and firefox) This question was triggered initially from the replicate javascript unsafe numbers in golang

Are JS engines allowed to change the bits of a NaN?
In JavaScript, the NaN value can be represented by a wide range of 64-bit doubles internally. Specifically, any double with the following bitwise representation: Is interpreted as a NaN. My question is: suppose I cast two 32-bit uints to a JS Number using ArrayBuffers, pass it around, then cast it back to two 32-bit uints. Will the recovered bits be
Is there any way to see a number in it’s 64 bit float IEEE754 representation
Javascript stores all numbers as double-precision 64-bit format IEEE 754 values according to the spec: The Number type has exactly 18437736874454810627 (that is, 264−253+3) values, representing the double-precision 64-bit format IEEE 754 values as specified in the IEEE Standard for Binary Floating-Point Arithmetic Is there any way to see the number in this form in Javascript?
