Debug Server Scripting (DSS) - precision "loss" when a value is printed/ written to a file

Hey there!

I am using Debug Server Scripting to evaluate an expression, in my case it is a variable:

input_val = activeDS.expression.evaluate("ll_in1")

Unfortunately I am facing a "precision loss" when printing the value/ writing it to a file. This can be reproduced using the following commands:

js:> input_val

-4615967861030116837

js:> print( input_val )

-4615967861030116000

js:> print( input_val.toString() )

-4615967861030116000

The three least significant decimal numbers are set to zeros.

The same is for file.write( str );

I really need the exact numbers. Does anybody know where this issue comes from (JavaScript data handling?) and how it can be solved?

Edit: FYI I am currently using the CCS-internal Scripting Console, but the script originally is called by a batch file calling the dss.bat on a Windows machine.

Edit 2: Seems to be JavaScript. I tried a "dirty workaround", but it does not work as expected:

     var num = -4615967861030116837;
    var d = 1e5;
    var head = parseInt( num/d );
    var tail = parseInt( num % d );

js:> head

-4.6159678610301E13

js:> tail

-16352.0

js:> num

-4.6159678610301164E18

Thank you,
Matthias
