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)
      }
}
