Abstract:

An analysis has been performed of the accuracy of the mathematical functions in the Basic monitor of the ZX81 and BBC microprocessors. The tests used for this are those that are part of the NPLUniversity of Tasmania Pascal validation suite. The results of these tests shows that even the smallest of microprocessors can be expected to give mathematically sound values for the standard functions.
