blosc2.expm1#

blosc2.expm1(ndarr: NDArray | NDField | C2Array | LazyExpr, /) → LazyExpr#

Calculate exp(ndarr) - 1 for all elements in the array.

Parameters:: ndarr¶ (NDArray or NDField or C2Array or LazyExpr) – The input array.
Returns:: out – A lazy expression representing exp(ndarr) - 1 of the input array. The result can be evaluated.
Return type:: LazyExpr

>>> result = result_lazy[:]
>>> print("Original values:", values)
