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

Operator

General description, example of use 

Comparison operators

> 

Comparison operator—greater.

See example in Description of operators

< 

Comparison operator—less.

See example in Description of operators

Arithmetic operators

+

Addition operator. Example of 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 operator. Example of 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 operator. Example of 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 operator. Example of 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 of 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 of use.

OnEvent ("MACRO","1","RUN")
{
 x=100/((5*8)/1.028);
}

Logical operators

&&

Logical AND operator. Example of 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 of use:

OnEvent ("CAM",N,"MD_START")
{
 if(!(strequal(N,"1",)))
 {
 DoReact("GRELE","1",""ON)
 }
else
 {
 DoReact("GRELE","2",""ON)
 }
}
