Apparently the number 1 / 998001 has "gone viral" (see video below).

To join in the craze I wrote a small sketch that reproduces this on the Arduino Uno:

Code: [Select]

#include "BigNumber.h"
// display it
void printBignum (BigNumber & n)
{
  char * s = n.toString ();
  char * p = s;
  int count = -2;
  while (*p)
    {
    Serial.write (*p);
    if (count % 3 == 2)
      Serial.print (" ");
    if (++count >= 60)
      {
      Serial.println ();
      Serial.print ("  ");
      count = 0;
      }
    p++;
    }  // end of while
  free (s);
}  // end of printBignum

void setup ()
{
  Serial.begin (115200);
  Serial.println ();
  BigNumber::begin (600);  // initialize library
  BigNumber result = BigNumber (1) / BigNumber ("998001");
  printBignum (result);
}  // end of setup

void loop () { }

Interesting, huh?

You can do something similar on a calculator. Try: 1 รท 81

The video explains why "8" isn't there.
