Addition
-
Subtraction
*
Multiplication
/
Division
Notice:
(type INT)/(type INT)=(type REAL); example: 3/4 = 0.75
DIV
Division, for variable type INT and REAL
Notice:
(type INT)DIV(type INT)=(type INT); example: 3 DIV 4 = 0
MOD
Modulo division (only for type INT) supplies remainder of an
INT division
Example: 3 MOD 4 = 3
