2 Operators
The following operators are supported within math expressions:
| Operator | Description |
|---|---|
| * | Multiplication. |
| / | Division. |
| % | Modulus: Divides two values and returns the remainder. |
| + | Addition. |
| - | Subtraction. |
| ^ | Either exponentiation (the default) or bitwise XOR. For exponentiation, the number in front of ^ is the base, the number after it is the power to raise it to. |
| ** | Exponentiation. (This is an alias for ^) |
| < | Less than. |
| > | Greater than. |
| >= | Greater than or equal to. |
| <= | Less than or equal to. |
| = | Equals. |
| == | Equals. (This is an alias for =) |
| <> | Not equal to. |
| != | Not equal to. (This is an alias for <>) |
| & | Either logical (the default) or bitwise conjunction (AND). |
| && | Logical conjunction (AND). |
| | | Either Logical (the default) or bitwise alternative (OR). |
| || | Logical alternative (OR). |
| ( ) | Groups sub-expressions, overriding the order of operations. |
| ~ | Bitwise NOT. |
<< |
Bitwise left shift. |
>> |
Bitwise right shift. |
<<< |
Bitwise left rotate. (Only available if compiled as C++20.) |
>>> |
Bitwise right rotate. (Only available if compiled as C++20.) |
Define TE_BITWISE_OPERATORS to enable bitwise behavior for &, |, and ^.
For operators, the order of precedence is:
| Operator | Description |
|---|---|
| ( ) | Instructions in parentheses are executed first. (If TE_BRACKETS_AS_PARENS is defined, then [] are treated the same way.) |
| +, -, ~ | Positive or negative sign for a value, and bitwise NOT. |
| ^ | Exponentiation. |
| *, /, and % | Multiplication, division, and modulus. |
| + and - | Addition and subtraction. |
<<, >>, <<<, >>> |
Bitwise left and right shift and rotation. |
| <, >, >=, <= | Relational comparisons. |
| = and != | Equality comparisons. |
| && | Logical conjunction (AND). |
| || | Logical alternative (OR). |
| & | Bitwise AND (if TE_BITWISE_OPERATORS is defined). |
| ^ | Bitwise XOR (if TE_BITWISE_OPERATORS is defined). |
| | | Bitwise OR (if TE_BITWISE_OPERATORS is defined). |
Defining TE_FLOAT will disable all bitwise functions and operators.
For example, the following:
5+5+5/2
Will yield 12.5. 5/2 is executed first, then added to the other fives. However, by using parentheses:
(5+5+5)/2
You can override it so that the additions happen first (resulting in 15), followed by the division (finally yielding 7.5). Likewise, (2+5)^2 will yield 49 (7 squared), while 2+5^2 will yield 27 (5 squared, plus 2).
Compatibility Note
The % character acts as a modulus operator in TinyExpr++, which is different from most spreadsheet programs. In programs such as LibreOffice Calc and Excel, % is used to convert a number to a percentage. For example, =20% would yield 0.20 in Excel. In TinyExpr++, however, 20% will result in a syntax error as it is expecting a binary (modulus) operation.
