Printing high digits error.

[Rocky]

Its been a while since i coded. :/

Code Select Expand

local i=0.000000000000000000000000000001;
Calc = format("%.30f", i );
print( Calc );
OUTPUT: 0.000000000000000000000000000001

However this doesn't work:

Code Select Expand

local i=0.001000000000000000000000000001;
Calc = format("%.30f", i );
print( Calc );
OUTPUT: 0.0010000000474974513000000000

Don't ask me why i need to use these high numbers. I just need to :X

Welcome to floating point precision issues. That's very normal behavior.

To solve this you need to store them in a string. Also you cant do math functions directly, i.e. you cant do
[spoiler=Beware, assembly ahead]add eax 0.0010000000000000000001[/spoiler]
you need to use your own add function which stores data in strings or to the hard drive instead of the memory

Wrong link. This is not an overflow. That's just how floating point numbers work.

It must have a name. I dont think it has a name.
Its most closely related with an overflow IMO

Any way i can counter this in squirrel or i don't really have to use squirrel to do what i am doing right now since its a bit unrelated to vc-mp (some experiments).  So, Just wondering if this issue is present in all languages such as C, Java etc as well.

If i'm right Arithmetic overflow generally refers to when trying to store some value that is too large to be represented within the available storage space of a certain variable. (I've lost touch so i'm not completely sure about these terms.)

Squirrel is created in C/C++. Therefore, this issue with floats comes from C/C++. There's nothing you can do about it.

Your only option here is to move to x64 architecture where integers have a range of -9223372036854775808 to 9223372036854775807. Or, if you need long floating point numbers. Compile the plugin your self and force Squirrel to use double floating point precision (doubles).


I remember I had this issue as well when I was working on my plugin. And as a workaround for the x32 bit systems I simply made 2 helper classes that can encapsulate x64 bit integers.

Ex:

Code Select Expand

local s = SLongInt("2165125312309463", 0);
print(s);
s += SLongInt(2);
print(s);
Output:

Code Select Expand

[USR] 2165125312309463
[USR] 2165125312309465
However, I need to revise it to make it seem like it's a part of the language. This was just a test.
