Important: Precaution must be taken when performing calculations within
the brackets [] following a mathematical function. The operations within
the bracket are performed first, and then the function is performed on this
resultant.
Example 28.5
Precaution for Order of Operation
N1#1=1.6; Parameter #1 is set at 1.6
N2#2=2.8; Parameter #2 is set at 2.8
N3#3=ROUND[#1+#2]; Parameter #3 is set at 4.0
Note that the values composing parameter #3 are added together first and
then rounded, not rounded and then added together.
