    Hi everybody,

    I know there is an implementation of BigInteger in the System.Numerics assembly of .NET 4.
    I need to use them inside my Unity project, but I cannot import the assembly in my project. If I use the instruction using, the compiler throws an error telling me it cannot find the assembly. So I looked up the directory of the System.Numerics.dll file and added it to my Unity project, but Unity itself throws two errors in the console.

    My question is: is there a way to include this assembly (this was added in C# 4 and .NET4) or have I to find a Unity implementation for it?

    Thanks in advance.

    Can you not just use 'long' or 'ulong'?

    Well, I do not think they are able to manage the high numbers I need... :(
    I have already thought if there was an alternative, but I need BigIntegers because I do need precision.

    Keep in mind (I suspect this is the source of your problem) that Unity uses Mono, and not .NET. Mono probably does not have this class implemented.

    Try using something like dotPeek to crack open the assembly and recreate it from scratch.

    Your number has to go beyond –9,223,372,036,854,775,808 to 9,223,372,036,854,775,807?

    Ok, Thanks a lot!

    I've solved. I splitted up the space into "small" cubes so I do not need BigIntegers anymore... I'll use longs... Thanks a lot!!
