Hey TeX uses 32 bit coordinates which an unit which is way
smaller than PCB and the maximum paper size is around 10 
meter IIRC (with a ~5nm resolution).

32 bit (actually 31, there is a sign) gives a large 
range for linear dimensions: 2^31 times the lattice
spacing of silicon is a bit above 1 meter. So 32 bit
is sufficient for the largest chips.
