def expm1(data=None, name=None, attr=None, out=None, **kwargs):
    """Returns ``exp(x) - 1`` computed element-wise on the input.

    This function provides greater precision than ``exp(x) - 1`` for small values of ``x``.

    The storage type of ``expm1`` output depends upon the input storage type:

       - expm1(default) = default
       - expm1(row_sparse) = row_sparse
       - expm1(csr) = csr



    Defined in src/operator/tensor/elemwise_unary_op_logexp.cc:L224

    Parameters
    ----------
    data : Symbol
        The input array.

    name : string, optional.
        Name of the resulting symbol.

    Returns
    -------
    Symbol
        The result symbol.
