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 repr…

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…
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 Arith…
