tensorflow/core/kernels/clustering_ops.cc:61–64

Returns the smallest multiple of a that is not smaller than b.

// Returns the smallest multiple of a that is not smaller than b.

  return remainder == 0 ? b : (b + a - remainder);
}

// Returns a / b rounded up to the next higher integer.
int64 CeilOfRatio(int64 a, int64 b) { return (a + b - 1) / b; }
