Siddhi Inbuilt Aggregate Functions in wiki format

...

Syntax	`<long\|double> sum(<int\|long\|double\|float> arg)`
Extension Type	Aggregate Function
Description	Calculates the sum for all the events.
Parameter	The value that needs to be summed.
Return Type	Returns long if the input parameter type is `int` or `long`, and returns double if the input parameter type is `float` or `double.`
Examples	`sum(20`) returns the sum of 20s as a long value for each event arrival and expiry. `sum(temp)` returns the sum of all temp attributes based on each event arrival and expiry.

...

Syntax	`<double> avg(<int\|long\|double\|float> arg)`
Extension Type	Aggregate Function
Description	Calculates the average for all the events.
Parameter	`arg`: The value that need to be averaged.
Return Type	Returns the calculated average value as a double.
Example	`avg(temp)` returns the average temp value for all the events based on their arrival and expiry.

...

Syntax	`<int\|long\|double\|float> max(<int\|long\|double\|float> arg)`
Extension Type	Aggregate Function
Description	Returns the maximum value for all the events.
Parameter	`arg`: The value that needs to be compared to find the maximum value.
Return Type	Returns the maximum value in the same data type as the input.
Example	`max(temp)` returns the maximum temp value recorded for all the events based on their arrival and expiry.

Syntax	`<int\|long\|double\|float> min(<int\|long\|double\|float> arg)`
Extension Type	Aggregate Function
Description	Returns the minimum value for all the events.
Parameter	`arg`: The value that needs to be compared to find the minimum value.
Return Type	Returns the minimum value in the same type as the input.
Example	`min(temp)` returns the minimum temp value recorded for all the events based on their arrival and expiry.
