//The convert routine should hold a routine that converts the data to an integer (in eax)
//function declared as: cdecl int ConvertRoutine(unsigned char *input, PTR_UINT address);
//Note: Keep in mind that this routine can be called by multiple threads at the same time.
ConvertRoutine:
//jmp dllname.functionname
[64-bit]
//or manual:
//parameters: (64-bit)
//rcx=address of input
//rdx=address
mov eax,[rcx] //eax now contains the bytes 'input' pointed to
cdq
mov ecx, #1000
idiv ecx

[/64-bit]

//jmp dllname.functionname
//or manual:
//parameters: (32-bit)
push ebp
mov ebp,esp
//[ebp+8]=address of input
//[ebp+c]=address
//example:
mov eax,[ebp+8] //place the address that contains the bytes into eax
mov eax,[eax] //place the bytes into eax so it's handled as a normal 4 byte value
cdq
mov ecx, #1000
idiv ecx

//The convert back routine should hold a routine that converts the given integer back to a row of bytes (e.g when the user wats to write a new value)
//function declared as: cdecl void ConvertBackRoutine(int i, PTR_UINT address, unsigned char *output);
ConvertBackRoutine:
//jmp dllname.functionname
//or manual:

//parameters: (64-bit)
//ecx=input

//example:
imul ecx, #1000
mov [r8],ecx //place the integer at the 4 bytes pointed to by r8

ret

[32-bit]
//parameters: (32-bit)
push ebp
mov ebp,esp
//[ebp+8]=input
//[ebp+c]=address
//[ebp+10]=address of output
//example:
push eax
push ebx
mov eax,[ebp+8] //load the value into eax
imul eax, #1000
mov ebx,[ebp+10] //load the output address into ebx
mov [ebx],eax //write the value into the address
