no need to imagine this, this is already the case in this universe. at least if we're talking about actually computing something, not just writing down the equations on paper.

for example from everything we know at least so far there are some truly continuous non-quantized quantities yet all numerical solutions can ever produce is an ever increasingly good approximation of something.

some constants are irrational so we can never get true values of certain physical constants, etc...
