11.5.1 Arithmetic expressions
These are formed by combining functions and arithmetic, binary and trigonometric operators with
the constants and variables of the language.
The priorities of the operators and the way they can be associated determine how these expressions
are calculated:
Priority from highest to lowest To be associated
NOT, functions, - (negative) from right to left.
EXP, MOD from left to right.
* , / from left to right.
+,- (add, subtract) from left to right.
Relational operators from left to right.
AND, XOR from left to right.
OR from left to right.
Brackets should be used in order to clarify the order in which the expression is to be evaluated.
(P3 = P4/P5 - P6 * P7 - P8/P9 )
(P3 = (P4/P5)-(P6 * P7)-(P8/P9))
Using redundant or additional brackets will neither cause errors nor slow down the execution.
In functions, brackets must be used except when these are applied to a numerical constant, in which
case they are optional.
(SIN 45) (SIN (45)) they're both valid and equivalent.
(SIN 10+5) the same as ((SIN 10)+5).
Expressions can be used also to reference parameters and tables:
(P100 = P9)
(P100 = P(P7))
(P100 = P(P8 + SIN(P8 * 20)))
(P100 = ORGX 55)
(P100 = ORGX (12+P9))
(PLCM5008 = PLCM5008 OR 1)
; Selects single block execution mode (M5008=1)
(PLCM5010 = PLCM5010 AND $FFFFFFFE)
; Frees feedrate override (M5010=0)
