The table below lists and describes comparison, arithmetic and conditional operators.

Operator

General description, example use

Comparison operators

> 

Comparison operator – greater.

See example in Description of operators section.

< 

Comparison operator – greater.

See example in Description of operators section.

Arithmetic operators

+

Addition. Example use:

OnEvent ("MACRO","1","RUN")
{
 x=5;
 y=10;
 i=x+y;  // add strings, i.e. 5+10=510
 e=str(x+y); // add integers 5+10=15
}

-

Subtraction. Example use:

OnEvent ("MACRO","1","RUN")
 
{
 x=5;
 y=10;
 i=x-y;  //  subtract integers 5-10=-5
 e=str(x-y); // subtract integers 5-10=-5
}

*

Multiplication. Example use:

OnEvent ("MACRO","1","RUN")

 

{

 

x=5;

 

y=10;

 

i=x*y;  // multiply integers 5*10=50

 

e=str(x*y); // multiply integers 5*10=50

 

}

/

Division. Example use:

OnEvent ("MACRO","1","RUN")

 

{

 

x=5;

 

y=10;

 

i=x/y;  // divide integers 5/10=0.5

 

e=str(x/y); // divide integers 5/10=0.5

 

}

%

Remainder after integer division. Example use.

OnEvent ("MACRO","1","RUN")

 

{

 

a=1120.0;

 

b=100;

 

e=a%b;  // remainder after integer division, i.e 1100 is divided by 100 and 20 is remainder.

 

// if there is division without remainder, then result is 0

 

}

( )

Group of arithmetic operators. Example use.

OnEvent ("MACRO","1","RUN")

 

{

 

x=100/((5*8)/1.028);

 

}

Logical operators

 

&&

Logical AND operator. Example use:

OnEvent ("MACRO","1","RUN")

 

{

 

a=1;

 

b=2;

 

z=3;

 

if((a<b)&&(b<z)) {y=1; //if false, then else

 

}

 

else {x=0;}

 

}

!

Logical inversion operator. Example use:

OnEvent ("CAM",N,"MD_START")

 

{

 

if(!(strequal(N,”1”,)))

 

            {

 

             DoReact(“GRELE”,”1”,””ON)

 

             }

 

else

 

            {

 

             DoReact(“GRELE”,”2”,””ON)

 

             }

 

}
