<DOUBLE> math:log10(<INT|LONG|FLOAT|DOUBLE> p1)
Query Parameters
| Name | Description | Default Value | Possible Data Types | Optional | Dynamic |
|---|---|---|---|---|---|
| p1 | The value of the parameter whose base 10 logarithm should be found. | INT LONG FLOAT DOUBLE | No | Yes |
Example 1
CREATE STREAM InValueStream (inValue double);
insert into OutMediationStream
select math:log10(inValue) as lnValue
from InValueStream;
If the inValue in the input stream is given, the function calculates the base 10 logarithm of the same and directs the result to the output stream, OutMediatioStream. For example, log10(19.234) returns 1.2840696117100832.
