Arithmetic operators
Use
The arithmetic operators are:
  • "+": Addition (numeric value or string)
  • "-": Subtraction (numeric value)
  • "*": Multiplication
  • "/": Division
  • "++": Increment (numeric value)
  • "--": Decrement (numeric value)
  • "+=": Adding a value to the variable or to the control (numeric or text)
  • "-=": Subtracting a value from the variable or from the control (numeric)
  • Modulo: Returns the remainder of a division
  • "^": Power (equivalent to Power)
Rules

Calculation rules

The different calculations are performed without loss of precision and without being truncated. The flow checks are performed when the result is assigned to a variable.
Notes

Displaying the result

The result of the calculation cannot be directly displayed by the following operators:
  • "++": Increment
  • "--": Decrement
  • "+=": Adding a value to the variable or to the control (numeric or text)
  • "-=": Subtracting a value from the variable or from the control (numeric)
Therefore, this example generates an error during the compilation:
num is int = 10
Trace(num+=1)
To display the result, perform the following modifications:
num is int = 10
num += 1
Trace(num)

Equivalence

  • j ++ is equivalent to j = j + 1
  • j -- is equivalent to j = j - 1
  • j += 3 is equivalent to j = j + 3
  • j -= 3 is equivalent to j = j - 3
We recommend that you use the following syntaxes: "j ++", "j --", "j +=" and "j -=", that are faster than the usual syntaxes.
