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)
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. Displaying the result The result of the calculation can be directly displayed using the following operators:- "++": Increment
- "--": Decrement
When the ++ (--) operator is used as an expression (e.g.: Info(x++)), its behavior is determined by the position of the operator, relative to the incremented variable: - ++x (--x) => increments (decrements) x then returns x.
- x++ (x--) => returns the value of x then increments (decrements) x.
For example:
let x is int = 5
Trace(x++) // Displays 5. x is set to 6
Trace(++x) // Displays 7. x is set to 7
Trace(--x) // Displays 6. x is set to 6
Trace(x--) // Displays 6. x is set to 5
Trace(x) // Displays 5
The result of the calculation cannot be directly displayed by the following operators: - "+=": 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.
