Floating point representation: IEEE 754 format and arithmetic explained
Computers store real numbers in a fixed number of bits, so they cannot store every real number exactly. Floating point packs a huge range of magnitudes into 32 or 64 bits by trading away some precision, and IEEE 754 is the standard almost every processor follows. This topic is a dependable source of encoding and precision questions, all resting on the same field layout and normalization rule.
