'sum' method for Numo::RObject returns wrong value #169

The "sum" method of "Numo::RObject", which contains the number, returns a strange value.

require "numo/narray"

p Numo::RObject.cast([1, 2, 3]).sum
#=> 13 (should be 6)

p Numo::RObject.cast([1.0, 2.0, 3.0]).sum
#=> 54043195528445954 (should be 6.0)

Is this behavior only occurring in my environment,

MacOS 10.14
Ruby 2.6.2p47 built with Apple clang version 11.0.0 (clang-1100.0.33.16)
numo-narray-0.9.1.8
