- : Subtraction Operator

Subtract one numeric value from another.

Syntax

{{operand1 - operand2}}

Precedence

Priority level in expression evaluation (1 = highest, 10 = lowest): 5

Evaluated after: ^, *, /, %

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

Operands

Returns

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

The difference between the left and right operands.

Examples

Basic Subtraction

<p>Discount: ${{model.originalPrice - model.salePrice}}</p>

Data:

doc.Params["model"] = new {
    originalPrice = 99.99m,
    salePrice = 79.99m
};

Output:

<p>Discount: $20</p>

Calculating Remaining Stock

<p>Remaining: {{model.totalStock - model.soldQuantity}} units</p>

Data:

doc.Params["model"] = new {
    totalStock = 500,
    soldQuantity = 347
};

Output:

<p>Remaining: 153 units</p>

Date Difference (with days)

<p>Days remaining: {{daysBetween(model.today, model.deadline)}}</p>

Variance Calculation

<p>Variance: {{model.actual - model.expected}}</p>
{{#if model.actual - model.expected > 0}}
  <span class="positive">Above target</span>
{{else}}
  <span class="negative">Below target</span>
{{/if}}

Data:

doc.Params["model"] = new {
    actual = 125000m,
    expected = 100000m
};

Output:

<p>Variance: 25000</p>
<span class="positive">Above target</span>

Combined with Other Operators

<!-- Discount percentage -->
<p>Save: {{format((model.originalPrice - model.salePrice) / model.originalPrice * 100, '0')}}%</p>

<!-- Net profit -->
<p>Profit: ${{format(model.revenue - model.costs - model.taxes, '0.00')}}</p>

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
• For absolute difference, use abs(a - b)
• Cannot subtract non-numeric types
• Date subtraction should use date/time functions like daysBetween()
