1.6 1.6 Arithmetic operations/functions
Function
The arithmetic functions are primarily for R parameters and variables (or constants and
functions) of type REAL. The types INT and CHAR are also permitted.
Arithmetic function ATAN2( , )
The function calculates the angle of the total vector from two mutually orthogonal vectors.
The result is in one of four quadrants (–° < 0 < +180°). The angular reference is always
based on the 2nd value in the positive direction.

Programming
The usual mathematical notation is used for arithmetic operations. Priorities for execution are
indicated by parentheses. Angles are specified for trigonometry functions and their inverse
functions (right angle = 90°).
