conv (Function)
This function converts a from the fromBase base to the toBase base.
Syntax
<STRING> math:conv(<STRING> a, <INT> from.base, <INT> to.base)
Query Parameters
| Name | Description | Default Value | Possible Data Types | Optional | Dynamic |
|---|---|---|---|---|---|
| a | The value whose base should be changed. Input should be given as a String. | STRING | No | Yes | |
| from.base | The source base of the input parameter a. | INT | No | Yes | |
| to.base | The target base that the input parameter a should be converted into. | INT | No | Yes |
Example 1
CREATE STREAM InValueStream (inValue string,fromBase int,toBase int);
insert into OutMediationStream
select math:conv(inValue,fromBase,toBase) as convertedValue
from InValueStrea;
If the inValue in the input stream is given, and the base in which it currently resides in and the base to which it should be converted to is specified, the function converts it into a string in the target base and directs it to the output stream, OutMediationStream. For example, conv("7f", 16, 10) returns "127".
