Arithmetic Operators
Arithmetic operators in DataLogic-rs perform mathematical calculations and return numeric results.
+ (Addition)
Adds multiple values together. Only works with values that can be coerced to numbers. For string concatenation, use the cat operator instead.
Syntax
{ "+": [value1, value2, ...] }Parameters
| Parameter | Description |
|---|---|
| value1, value2, ... | Numeric values to add together |

- (Subtraction)
Subtracts values from the first value. If only one value is provided, it negates that value.
Syntax
{ "-": [value1, value2, ...] }Parameters
| Parameter | Description |
|---|---|
| value1 | Value to subtract from |
| value2, ... | Values to subtract |

* (Multiplication)
Multiplies values together.
Syntax
{ "*": [value1, value2, ...] }Parameters
| Parameter | Description |
|---|---|
| value1, value2, ... | Values to multiply together |

/ (Division)
Divides the first value by all subsequent values.
Syntax
{ "/": [value1, value2, ...] }Parameters
| Parameter | Description |
|---|---|
| value1 | Dividend |
| value2, ... | Divisors |

% (Modulo)
Returns the remainder after dividing the first value by the second value.
Syntax
{ "%": [value1, value2] }Parameters
| Parameter | Description |
|---|---|
| value1 | Dividend |
| value2 | Divisor |

Rule:
Data:
Result:
max
Returns the largest value from a list of values.
Syntax
{ "max": [value1, value2, ...] }Parameters
| Parameter | Description |
|---|---|

Result:
abs (Absolute Value)
Returns the absolute value of a number or an array of numbers. The absolute value is the non-negative value of a number without regard to its sign.
Syntax
{ "abs": value }{ "abs": [value1, value2, ...] }Parameters
| Parameter | Description |
|---|---|
| value | A numeric value to compute the absolute value of |
