No, there is officially no function, but you can define a new one that does the job pretty well.

Here is the prototype that goes before the program "begin".

function avg_zeros(x:numeric)
; compute average not considering zeros,
; --> in:  rain rate
; <-- out: average rain rate
local N
begin
 N=num(x .ne. 0)
 return(sum(x)/ N)
end

Example of a function call

rain=avg_zeros(ts->precp_r)

Cheers
