IEEE 754 Floating Point Calculator

About This Tool

The IEEE 754 Floating Point Calculator is a powerful online tool designed to simulate and analyze the binary representation of decimal numbers according to the IEEE 754 standard. It enables users to input a decimal number and select custom or standard floating-point formats, including single and double precision. The calculator then computes the binary layout, displaying the sign, exponent, and fraction bits in a clear format. Additionally, it allows decoding of existing binary strings back into human-readable decimal numbers. This tool is ideal for students learning about floating-point arithmetic, software developers working with binary data encoding, and educators illustrating how decimal numbers are stored in computers. Its features include detailed step-by-step explanations of the conversion process, visualization of each bit's function, and the capability to handle special cases such as zero, infinity, or NaN. Designed with a modern interface, the calculator is responsive and accessible, supporting high contrast modes and keyboard navigation for inclusivity. Users can copy results, export data, or toggle visualization options for better understanding. Whether you're debugging numerical algorithms or teaching computer architecture, this online IEEE 754 calculator provides accurate, easy-to-understand insights into floating-point number representation.
