Arithmetic operations/functions

Arithmetic functions are used predominantly for R
parameters and variables (or constants and functions)
of the type REAL. The types INT and CHAR are also
permitted.
Standard mathematical notation is used in arithmetic
operations. Priorities for execution are indicated by
parentheses. Angles are specified for trigonometry
functions and their inverse functions (right angle = 90°).

Caution: (Type INT)DIV(Type INT)=(Type INT); Example: 3 DIV 4 = 0
Modulo division (INT or REAL) produces the remainder of an INT division,
e.g. 3 MOD 4=3
