The largest number representable in 64 bits
Summary
A technical exploration of the largest number representable in 64 bits, expanding beyond fixed data types to programmable representations, Busy Beaver variants, and lambda calculus encodings. It discusses the 2^64-1 limit for uint64_t as the maximum unsigned 64-bit integer, compares with 64-bit floating point max, and then introduces ideas about representing large numbers through tiny programs in languages like C, bc, and lambda calculus, culminating in Melo’s Number that exceeds Graham’s Number.
