e()

None.

Type: Double

The value of e (approximately 2.71828182845905).

<p>Euler's number: {{format(e(), '0.00000')}}</p>

Output:

<p>Euler's number: 2.71828</p>

<p>Result: {{format(model.initial * pow(e(), model.rate * model.time), '0.00')}}</p>

Data:

doc.Params["model"] = new {
    initial = 100,
    rate = 0.05,
    time = 10
};

Output:

<p>Result: 164.87</p>

<!-- e^2 using constant vs exp function -->
<p>e^2 = {{format(pow(e(), 2), '0.000')}}</p>
<p>exp(2) = {{format(exp(2), '0.000')}}</p>

Output:

<p>e^2 = 7.389</p>
<p>exp(2) = 7.389</p>
