SoftMaker Basic supports the following operators:
Arithmetic operators
Operator |
Function |
Example |
+ |
Addition |
x = a + b |
- |
Subtraction |
x = a - b |
|
also: Negation |
x = -a |
* |
Multiplication |
x = a * 3 |
/ |
Division |
x = a / b |
Mod |
Modulo |
x = a Mod b% |
^ |
Exponentiation |
x = a ^ b |
String operators
Operator |
Function |
Example |
+ |
Concatenation |
x = "Good " + "Day" |
& |
Concatenation |
x = "Good " & "Day" |
The difference between the operators + and & is in the handling of variant variables that contain numbers: the + operator adds these numbers, whereas the & operator concatenates them as strings (see example).
Example:
Sub Main
Dim a, b as Variant ' 2 variant variables
a = 2
b = 3
Print a + b ' Return the number 5
Print a & b ' Returns the string "23"
End Sub
Comparison operators
Operator |
Function |
Example |
< |
Less than |
If x < y Then ... |
<= |
Less than or equal to |
If x <= y Then ... |
= |
Equal to |
If x = y Then ... |
>= |
Greater than or equal to |
If x >= y Then ... |
> |
Greater than |
If x > y Then ... |
<> |
Not equal to |
If x <> y Then ... |
The result of comparisons with these operators is an Integer value:
▪-1 (True) if the condition applies
▪0 (False) if the condition does not apply
Logical and bitwise operators
Operator |
Function |
Example |
Not |
Logical negation |
If Not (x = a) Then ... |
And |
Logical And |
If (x > a) And (x < b) Then ... |
Or |
Logical Or |
If (x = y) Or (x = z) Then ... |
These operators work bitwise. This means that you can use them for logic testing as well as for bitwise operations.
Precedence of operators
Operators are processed in the following order:
