Template:Calcsubtract
From Wikipedia, the free encyclopedia
This basic template just evaluated and returns difference between the first parameter and the sum of its other parameters (up to 4 parameters). Missing or empty parameters are ignored (treated like zero). The parameters can also be numeric expressions that will be evaluated before adding them (this alternate form allows adding more values and simplifies the use of this template in other computing templates). This template returns 0 if all parameters are empty or missing.
- Syntax:
- {{Calcsubtract|[value1]|[value2]|[value3]|[value4]}}
- Note:
- Using this template is generally not necessary, as the following syntaxes are similar and equivalent:
- {{Calcsubtract|value1|value2}}
- {{Sum|value1|-value2}}
- {{#expr:value1-value2}}
- Use this template only for parameters that may be conditionally empty as they are tested and ignored.
