do you understand mod???
mod finds you the remainder...
since 4 isn't dividisble by 6 or 8... the remainder is going to be 4... its simple math.
Computer Science Canada 4 mod 6 = 4? 4 mod 8 = 4? |

4 mod 6 = 4? 4 mod 8 = 4? y does this happen? i though mod returned a remainder |

er... perhaps because you are trying to get the remainder when 4 is divided by 6... which just so happens to be 4 as 4 is not divisible by 6... The same is true for 4 mod 8. If you are trying to get the remainder when 8 is divided by four then you should be using 8 mod 4. If you still don't understand what's going on (and this isn't much of a description i must admit...) then I would recoment the ever helpful google. |

if your jus trying to divide its probably easier to us div (not recommended for int) |

div works with int and it probably the best to use cause it rounds it to closes integer, / on the other hand doesnt |

Careful: Turing Help Reference wrote: The div operator divides one number by another and produces the integer result, truncated in the direction of zero. For example, 7 div 2 produces 3 and -7 div 2 produces -3.
