Centipawns

a score unit which corresponds approximately to **one hundredth** of a pawn unit. [|Fixed point] representation with centipawn fractions allows a smooth relation of all piece values with a reasonable granularity to distinguish positional scores. 16 or even 15 bits are sufficient to store signed centipawn ranges in hash tables, while sign extension to the common 32-bit integer range is convenient to avoid overflows in scaling terms like in the tapered eval, even with an internal finer granularity used inside the evaluation. || toc =Quotes=
