Binary Arithmetic Operators
InstallShield 2020 ยป InstallScript Language Reference
The InstallScript compiler recognizes the binary arithmetic operators listed in the following table.
|
Symbol |
Operation |
Example |
Description |
|
+ |
Addition |
x + y |
Adds two operands. |
|
- |
Subtraction |
x - y |
Subtracts the second operand from the first operand. |
|
* |
Multiplication |
x * y |
Multiplies two operands. |
|
/ |
Division |
x / y |
Divides the first operand by the second operand. Because InstallShield does not have floating-point data types, the fractional part of the answer is dropped. For example, 5/2 = 2.5 --> 2. |
|
% |
Modulus |
19 % 5 |
Divides the first operand by the second operand and returns the remainder. For example, nResult = 19 % 5; results in nResult = 4. |
Tip:You should include a space both before and after an arithmetic operator to make your script more readable and to maintain a consistent appearance.
