Class Power

Namespace

YndigoBlue.Velocity.Functions

Assembly

YndigoBlue.Velocity.dll

Represents the POWER mathematical function that raises a base number to a specified exponent.

public class Power : Function, ICheckItem, IDefaultItem, IFilterItem, IElement

Power

Implements

ICheckItem

IDefaultItem

IFilterItem

IElement

Remarks

The POWER function calculates base^exponent. For example, POWER(2, 3) returns 8, POWER(10, -2) returns 0.01. This is useful for exponential growth calculations, scientific computations, and mathematical modeling. Note that certain combinations (like negative base with fractional exponent) may produce errors.

Examples

Compute the squared value of each measurement:

var schema = manager.LoadSchema("measurements");
var readings = schema["readings"];

var query = new Query()
    .Select([ readings["id"], new Expression("squared", new Power(readings["value"], 2.0)) ])
    .From(readings);

var results = manager.Retrieve(query);
