e

Description

Returns Euler’s number e, a mathematical constant approximately equal to 2.718281828459045. This value is limited to 15 decimal places.

Syntax

Example

Use case: Model exponential growth

Use e in combination with logarithms and powers to calculate predictive growth models. In this example, we calculate the growth rate and then predict the value 10 hours into the future.

Example data

{
    "initial_value": 500,
    "current_value": 1000,
    "time_since_start_hours": 10
}

Example query

create prediction_in_ten_hours from (initial_value * power(e(), growth_rate * (time_since_start_hours + 10)))

Example output

{
    "initial_value": 500,
    "current_value": 1000,
    "time_since_start_hours": 10,
    "growth_rate": 0.0693,
    "prediction_in_ten_hours": 1999.41
}
