What is meant by accuracy of analog computer?Analog computers have accuracy of 0.01% to 2%?

I can't understand what are they saying? What's accuracy in this case of analog computer? I mean 0.01% accuracy is 99.99% not accurate. This can't be real. Right?
Full text is taken from "inadequate accuracy" of Narsingh Deo "System simulation with digital computer". This is surprisingly a good book, I didn't expect this to be a source for learning as most books written by local authors used to be garbage.

In general, the result from a digital simulation is more accurate than that from an analog simulation. The accuracy of analog simulation depends on the accuracy of the components being used which can vary from 0.01% to 2%. When accuracy required of components is more than 0.1%, the cost of components increases rapidly. An accuracy of about 1% for a simulation of a system with modest complexity is considered good.

Hi,

meant is the "accuracy_error" to be +/- 0.01% to +/- 2%
