sqrt

Input Stack: expr: TimeSeriesExpr

⇨

Output Stack: TimeSeriesExpr

Compute a new time series where each interval has the square root of the value from the input time series. For negative values, the result is NaN following standard mathematical conventions.

Parameters

• expr: The time series expression to take the square root of

Examples

Demonstrating square root with different constant values:

0	64	-64
0,:sqrt	64,:sqrt	-64,:sqrt

The examples show that √0 = 0, √64 = 8, and √(-64) = NaN.
