Numbers Held Inexactly on the ZX81 (Part 1)

First part of a series examining floating-point representation errors in the ZX81 8K ROM. Focuses on integer powers of 2 and how the ZX81 stores them, with programs to examine raw floating-point bytes and demonstrate inaccuracies at specific powers (13, 26, 27, 31, 52-54, 61, 62, etc.).
