To this end, we use the Newton series to analytically continue in $N$ the partition functions for string orbifolds on $\\mathbb{C}/\\mathbb{Z}_N$ conical spaces, known for all odd integer $N$. In the concrete example of ten-dimensional Type-IIB strings, the one-loop partition function can be computed explicitly and the one-loop entropy can be expressed as a manifestly modular invariant series in terms of the Weierstrass $\\wp$ function.
