Working with big number variables

[teufel]

Dear Support,

if I will convert my 2863000600000005 string with String.ToNumber(Target); I'm getting as result 2.863e+015 instead of 2863000600000005 number...
How can i resolve this kind of "bug"?

Thank you

Why is it problem?
Because I would convert is back to string, but in this case can not :(

If you are telling it to convert to a number then that is what it has done, it isn't a bug just a limitation of the maths libraries used.
What you weren't expecting was that it would be as a 16bit value ( binary 1111111111111111 = max 65535) unless you reproduce the number in scientific notation which looses you some precision. 32bits still only gives you a max of 2,147,483,647, 64bits takes you to a max of 18,446,744,073,709,551,615.
If they are in variables with a different names then you have both values, it only changes when you call it a number.

You could use an arbitrary precision library, see attachment.

Thank you, it works
