When I worked with Data/Basic on Pick, -0 was used to represent infinity[1].
Add 1 and you got the largest positive number possible, subtract 1 and you
got the largest negative number possible.

It's part of the FPU (floating point unit). This can be an external
co-processor but usually is part of the main processor nowadays.

So if it is possible for the computer to handle infinity how and where is
it done ?
Processor or co-processor ?
