Reference to the exp() function

Summary

exp(<expression>)

Returns the natural exponential for each data value described by the expression.

Parameters

ParameterDescription
expression Expression specifying the powers to raise the constant e to.

Description

The exp() function produces a time series in which each data value is equal to e raised to the power specified by the expression.

  • If the expression describes a constant value N, then exp() returns a continuous series where every data value is eN.
  • If the expression describes one or more time series, then exp() returns a new time series for each input time series. Each value in a new time series is calculated as eV, where V is the value of the corresponding point in the input time series.

The inverse of this function is log().

By default, the chart legend displays a rounded version of the result. You can cause the legend to display the result with more precision by holding down the shift key when you hover over the time series.

Examples

In this example, we see the result (in red) of using exp(2) to raise e to the power 2. We also see the result (in blue) of obtaining the inverse by applying the log() function.

Here we see the result (in orange) of using exp() to obtain the natural exponential of a time series (in blue).
