You need to match the output type of the divide block (which is probably
float) _and_ you need to match the vector length of the divide block.
Best done with setting a parameter `vlength` and setting this as your
io_signature in the constructor:
`io_signature::make (1,  1, sizeof (float)*vlen)),`

This creates a block with a configurable vector length as input.
