Summary
pow(<base-tsExpression>, <exponent-tsExpression>[, inner])
Raises the base expression to the power of the exponent expression.
Parameters
| Parameter | Description |
|---|---|
| base-tsExpression | Expression describing a constant or a time series of values to be raised to the exponent. |
| exponent-tsExpression | Expression describing a constant or a time series of values to use as the exponent. |
| inner | Results in an inner join. |
Description
The pow() function produces a time series in which the data values are the values specified by the base expression, raised to a power specified by the exponent expression.
Either or both parameters may describe a time series or a constant value, and either may be fractional or negative. WQL does not support imaginary numbers, so pow(-1, 0.5) returns no data.
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
Here we see the result (in orange) of using pow() to raise the values of a time series (in blue) to the 3rd power. That is, for each data value v in the input series, the result series returns v3.
