WebThis standard specifies how single precision (32 bit) and double precision (64 bit) floating point numbers are to be represented, as well as how arithmetic should be carried out on them. The IEEE single precision floating point standard representation requires a 32 bit word, which may be represented as numbered from 0 to 31, left to right.

WebNov 28, 2024 · Floating-point numbers have several distinct "ranges": Standard/Normal arithmetic; Subnormal arithmetic; Infinite arithmetic; NaN arithmetic; Zero arithmetic; For instance, if I add any normal number to an infinite number, I need to get an infinite number back. If I add two large enough subnormals, I should get a normal number. WebThe IEEE 754 standard defines exactly how floating-point arithmetic is performed.
