MOD
 returns the remainder of the integer division of two numbers (rounded to integers before division is performed); Details: x MOD y  equals to  x - x \ y * y(to ROUND(x) - x \ y * ROUND(y) if x or y are not integer)
\
 returns the integer division of two numbers (rounded to integers before division is performed); Details: x \ y  equals to  FIX(x / y)(to FIX(ROUND(x) / ROUND(y)) if x or y are not integer)
