Compute a new time series where each interval has the value (a / b) where a
and b are the corresponding intervals in the input time series. If a and b are 0,
then 0 will be returned for the interval. If only b is 0, then NaN will be returned as
the value for the interval. Sample data:
:div
0.5
0.0
NaN
NaN
NaN
Input 1
1.0
0.0
1.0
1.0
NaN
Input 2
2.0
0.0
0.0
NaN
NaN
Use the fdiv operator to get strict floating point behavior.
