[julia-users] [Doc, IJulia, rc3] `cumsum` documentation problem?

[Sisyphuss]

Cumulative sum along a dimension ``dim`` (defaults to 1).
See also :func:`cumsum!` to use a preallocated output array,
both for performance and to control the precision of the
output (e.g. to avoid overflow).

cumsum cumsum! cumsum_kbn
