round() : Round to Nearest

Round a number to the nearest integer or specified decimal places.

Signature

round(value, decimals?)

Parameters

Returns

Type: Number

The rounded value.

Examples

Round to Integer

<p>Rounded: {{round(model.value)}}</p>

Data:

doc.Params["model"] = new {
    value = 19.6
};

Output:

<p>Rounded: 20</p>

Round to 2 Decimal Places

<p>Price: ${{round(model.price, 2)}}</p>

Data:

doc.Params["model"] = new {
    price = 19.995m
};

Output:

<p>Price: $20.00</p>

Round Percentage

<p>{{round((model.completed / model.total) * 100, 1)}}% complete</p>

Data:

doc.Params["model"] = new {
    completed = 17,
    total = 25
};

Output:

<p>68.0% complete</p>

Multiple Decimal Places

{{#each model.measurements}}
  <li>{{this.name}}: {{round(this.value, 3)}} mm</li>
{{/each}}

Data:

doc.Params["model"] = new {
    measurements = new[] {
        new { name = "Width", value = 12.3456 },
        new { name = "Height", value = 8.7654 }
    }
};

Output:

<li>Width: 12.346 mm</li>
<li>Height: 8.765 mm</li>

Notes

• Uses standard rounding (0.5 rounds up)
• Default is 0 decimal places (rounds to integer)
• Specify decimal places for precision
• For always rounding up, use ceiling()
• For always rounding down, use floor()
• For truncation without rounding, use truncate()
