About Computer Data Representation

Computer Data Representation - IEEE 754, two's complement, one's complement

A tool of computer data representation for computer science students and professionals. It supports IEEE 754 floating point numbers, two's complement and one's complement of integers. For IEEE 754, the actual represented value and representation error for a number are displayed for analysis. Binary data can be input conveniently by simply touching a digit to toggle it between 0 and 1.

Features:

- Easy input of binary data - touch a binary digit to toggle it

- IEEE 754 32-bit single precision and 64-bit double precision

- Display actual represented value and representation error

- Show Infinity, -Infinity, and NaN as appropriate

- Two's complement in 8-bit, 16-bit, 32-bit and 64-bit

- One's complement in 8-bit, 16-bit, 32-bit and 64-bit

- Out-of-range detection for two's and one's complement
