I'm working on a short plugin that translates a huge 64bit number into two other values by bit shifting. The process works great on a scientific calculator, but I have been unable to accomplish the task using Sourcemod.

The test code I developed will freeze the server and the client without providing any errors. I believe the number I'm using is too large for the '[EXTENSION] BigInteger compute with large numbers' that I installed. Link: https://forums.alliedmods.net/showthread.php?t=233938

Goal:
Given an input number of 5848670506169059306
It should produce a lowseed value of: 2021836778
It should also produce a highseed value of: 1361749718

Basically this is what I'm trying to achieve:

PHP Code:

    seed := 5848670506169059306
    high := seed >> 32
    low := (seed << 32) >> 32
    fmt.Println("Seed is: ", seed)
    fmt.Println("Seed low is: ", low)
    fmt.Println("Seed high is: ", high) 


However, that's not easy to do in Sourcemod. If the number is in fact too large for the BigInteger extension, how can I achieve the desired results without the extension?

Sourcemod code so far:

PHP Code:

#include <bigint>

#pragma semicolon 1
#pragma newdecls required

#define PLUGIN_VERSION "1.0"

public Plugin myinfo = 
{
    name = "[TF2] Test of seed import and translation",
    author = "PC Gamer",
    description = "Test importing large number with BigInt",
    version = PLUGIN_VERSION,
    url = "www.sourcemod.com"
}

public void OnPluginStart()
{
    RegConsoleCmd("sm_seed", Command_TestBigInt);
}

public Action Command_TestBigInt(int client, int args)
{
    char arg1[32];
    if (args < 1)
    {    
        ReplyToCommand(client, "seed <seed number>");
        ReplyToCommand(client, "Example: seed 5848670506169059306");    
        
        return Plugin_Handled;
    }
    GetCmdArg(1, arg1, sizeof(arg1));
    
    Handle hBigInt = BigInt_CreateFromString(arg1);
    Handle hNewBigIntLow = BigInt_BitShiftRight(BigInt_BitShiftLeft(hBigInt, 32), 32);
    Handle hNewBigIntHigh = BigInt_BitShiftLeft(hBigInt, 32);

    int lowseed = BigInt_ToInt(hNewBigIntLow); //expected result 2021836778 
    int highseed = BigInt_ToInt(hNewBigIntHigh); //expected result: 1361749718    
    
    PrintToChat(client, "Input seed provided by client: %s", arg1);
    PrintToChat(client, "Seed translates into: lowseed: %i, highseed: %i", lowseed, highseed);    

    delete hBigInt;
    delete hNewBigIntLow;
    delete hNewBigIntHigh;

    return Plugin_Handled;
}

I'll mark this one as solved. For whatever reason the use of the BigInt_BitShiftLeft was causing my server to freeze. As a result, I used a different function of BigInt_BitAnd to achieve the desired result. Very weird.
