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)

CEIL
returns the smallest integer greater than or equal to a numeric-expression (3.2 –> 4, 3.6 –> 4, -3.2 –> -3).
COS
returns the cosine of an angle given in radians.
EXP
