Use Array's type as return type for reduction fns #154
Description
The following functions currently return f64 values irrespective of the input Array data's native type.
-
sum_all -
sum_nan_all -
product_all -
product_nan_all -
min_all -
max_all -
all_true_all -
any_true_all -
count_all -
imin_all -
imax_all
The above functions need to return the appropriate type value instead of f64. This change is probably going to be
easier to implemented once Typed Arrays are implemented.
