* : Multiplication Operator

Summary

Multiply two numeric values together.

Syntax

{{operand1 * operand2}}

Precedence

Priority level in expression evaluation (1 = highest, 10 = lowest): 4

Evaluated after: ^

Evaluated before: +, -, <, <=, >, >=, ==, !=, ??, &&, ||

Operands

Returns

Type: Number (Int, Long, Double, or Decimal depending on operands)

The product of the left and right operands.

Examples

Line Item Total

<p>Total: ${{format(model.quantity * model.price, '0.00')}}</p>

Data:

doc.Params["model"] = new {
    quantity = 5,
    price = 19.99m
};

Output:

<p>Total: $99.95</p>

Area Calculation

<p>Area: {{model.width * model.height}} sq ft</p>

Data:

doc.Params["model"] = new {
    width = 12.5,
    height = 8.0
};

Output:

<p>Area: 100 sq ft</p>

Tax Calculation

<p>Subtotal: ${{format(model.price, '0.00')}}</p>
<p>Tax ({{model.taxRate * 100}}%): ${{format(model.price * model.taxRate, '0.00')}}</p>
<p>Total: ${{format(model.price * (1 + model.taxRate), '0.00')}}</p>

Data:

doc.Params["model"] = new {
    price = 100.00m,
    taxRate = 0.08m
};

Output:

<p>Subtotal: $100.00</p>
<p>Tax (8%): $8.00</p>
<p>Total: $108.00</p>

Percentage Calculation

<p>{{format(model.score / model.total * 100, '0.0')}}% correct</p>

Scaling Values

<!-- SVG bar chart with scaled heights -->
{{#each model.data}}
  <rect height="{{this.value * model.scaleFactor}}" />
{{/each}} 

Data:

doc.Params["model"] = new {
    data = new[] {
        new { value = 50 },
        new { value = 75 },
        new { value = 100 }
    },
    scaleFactor = 2
};

Notes

• Works with all numeric types (int, long, double, decimal)
• Result type depends on operand types (follows C# numeric promotion rules)
• Use parentheses to control order of operations
• Multiplication has higher precedence than addition/subtraction
• For exponentiation, use the ^ operator or pow() function
• Cannot multiply non-numeric types
