cmTomi (Function)

This converts the input given in centimeters into miles.

Syntax

<DOUBLE> unitconversion:cmTomi(<INT|LONG|FLOAT|DOUBLE> p1)

Query Parameters

Name	Description	Default Value	Possible Data Types	Optional	Dynamic
p1	The value that needs to be converted from centimeters into miles.		INT LONG FLOAT DOUBLE	No	Yes

Example 1

unitconversion:cmTomi(10000)

In this example, the unitconversion:cmTomi() function converts a value of 10,000 centimeters into its equivalent value in miles. The conversion result is approximately 0.062 miles.

Example 2

CREATE STREAM InputStream (length_cm double);
CREATE SINK STREAM OutputStream (length_cm double, length_mi double);

@info(name = 'lengthConversionQuery')
INSERT INTO OutputStream
SELECT length_cm, unitconversion:cmTomi(length_cm) AS length_mi
FROM InputStream;

In this example, an input stream called InputStream is created with a single attribute, length_cm, representing lengths in centimeters. Then, an output stream called OutputStream is defined, which will contain the original length in centimeters as well as the converted length in miles.

The lengthConversionQuery processes events from the InputStream. It uses the unitconversion:cmTomi() function to convert the length_cm attribute from the InputStream into its corresponding value in miles, and this value is assigned to the length_mi attribute in the OutputStream.

The query outputs the original length in centimeters and the converted length in miles for each event to the OutputStream.
