Handlebar Helper Function: Subtract
Subtracts two numeric arguments and returns their difference. The function can handle both integer and floating-point numbers, and attempts to convert strings to numbers.
Availability
This helper is available in the Winter ’26 release of Marketing Cloud Next (API version 65.0).
Syntax
1{{subtract value1 value2}}Parameters
| Parameter | Type | Description |
|---|---|---|
value1 | Number or String | Required. The first value to subtract from. Must be a number or convertible to a number. |
value2 | Number or String | Required. The second value to subtract. Must be a number or convertible to a number. |
Return Value
The function returns the arithmetic difference of the two input values. If you provide more than two arguments, the operation subtracts only the first two. The result is always a number rounded to 2 decimal places.
If either input is a string, the operation tries to convert it to a number. If a string value can’t be converted to a number, the operation throws an exception.
