Code:
int rand7()
{
  float r7=0;
  
  for(int i=0; i<7; i++)
  {
   r7+=rand5();
  }

  return int((r7/7)*2);
}


This ought to work unless I'm deluding myself.. however its probably not very elegant.. like all my code



you said earlier that this wouldnt work because *2 makes 1 impossible, what about if we modificate it a bit like this:

Code:
int rand7()
{
  float r7=0;
  
  for(int i=0; i<8; i++)
  {
   r7+=rand5();
  }

  return int(((r7/8)*2)-1);
}


wouldn't that work?
