I'm revisiting a question (How to test if numeric conversion will change value?) that as far as I was concerned was fully solved. The problem was to detect when a particular numeric value would overflow JavaScript's IEEE-754 Number type. The...
I am trying to convert some Java code into JavaScript which is needed for the application I am working on. I am stuck on one class and its methods that convert a variable of type double to long, and then long to a byte array that consists of 8 bytes...
Suppose I have a hex number "4072508200000000" and I want the floating point number that it represents (293.03173828125000) in IEEE-754 double format to be put into a JavaScript variable.  I can think of a way that uses some masking and a cal...
Since integers above 2^53 can't be accurately represented in doubles, how does JS decide on their decimal representation when they are printed as strings?  For example, 2^55 is 36028797018963968, and printf("%lf",(double)(1LL<<55))...
I am wondering how I can convert 1,000,000 to 1.0E6 in JavaScript. I'd like the complete opposite of the parseInt function?  Many thanks!...
Out of interest and not real life demands: Is it somehow possible to subtract exponents of two  numbers in JavaScript? Because the result of 1e+29 * 1e-3 (or 1e+29 / 1e+3) is the unprecise number 9.999999999999999e+25 even though the correct result 1...

Finance applications demand an integer type due to security reasons. Rounding errors are not acceptable in that kind of application and can lead to exploits. Since JavaScript doesn't offer a proper Integer type, only IEEE 754 Doubles, how do you...
