|
| Arithmetic operators | |
| + | Addition (A+B) |
|---|---|
| - | Subtraction (A-B) |
| * | Multiplication (A*B) |
| / | Division (A/B)Division by 0 causes error |
| MOD | Remainder (A MOD B)Division by 0 causes error |
| DIV | Integer Division (A DIV B) The fractional part of a quotient is rounded downDivision by 0 causes error |
String variables can be added or multiplied
- (e.g.) Adding String variables
- A$="ABC" : B$="XYZ" : PRINT A$+B$
Result: ABCXYZ
- (e.g.) Multiplying String variables
- A$="ABC" * 4: PRINT A$
Result: ABCABCABCABC
| Relational operators | |
| > | Value on left is greater than value on right (A>B) |
|---|---|
| < | Value on left is less than value on right (A<B) |
| >= | Value on left is equal or greater than value on right (A>=B) “=>” is invalid and does not work |
| <= | Value on left is equal or less than value on right (A<=B) “=<” is invalid and does not work |
| == | The values are equal (A==B) “=” assigns a value to a variable |
| != | The values are not equal (A!=B) “<>” is invalid and does not work |
| Bitwise operators | |
| AND | Logical AND (A AND B) |
|---|---|
| OR | Logical OR (A OR B) |
| XOR | Exclusive OR (A XOR B) |
| NOT | Negation (NOT A) |
| << | Left Arithmetic Shift (A << 1 shifts the value of A left by 1 bit) |
| >> | Right Arithmetic Shift (A >> 3 shifts the value of A right by 3 bits) |
| Logical Operators | |
| && | Logical AND (IF A<3 && B==2 THEN ～) |
|---|---|
