blosc2.arccos#

blosc2.arccos(ndarr: NDArray | NDField | C2Array | LazyExpr, /) → LazyExpr#

Compute the inverse cosine, element-wise.

Parameters:: ndarr¶ (NDArray or NDField or C2Array or LazyExpr) – The input array.
Returns:: out – A lazy expression representing the inverse cosine of the input array. The result can be evaluated.
Return type:: LazyExpr
