IEEE 754 Integer and Floating-Point Visualizer

See the bits behind a number

Compare IEEE 754 half-, single- and double-precision layouts with separate sign, exponent and mantissa fields. Integer input appears as 8-, 16-, 32- and 64-bit data with signed and unsigned interpretations.

Explore raw patterns interactively

• Toggle any bit and see the interpreted value update.
• Enter hexadecimal patterns for every displayed width.
• Compare wrapping, sign bits, overflow and special floating-point values.
• Use the view for development, teaching and low-level debugging.

Enter a number, compare the widths and then change bits or hex fields to test another pattern.

For development and computer-science learning

The tool is intended for software developers, students, educators and anyone learning how numbers are represented at bit level. It provides the interactive view without requiring a compiler, debugger or locally installed utility.

Local processing and limits

Everything is calculated locally and numeric input is not stored. The 16-bit floating-point conversion is an educational approximation with simplified rounding and subnormal handling. Integer values wrap independently to each width, and the app provides no file import, export or copy command. Invalid or incomplete numeric input is ignored without a visible validation message.

Text and hexadecimal fields are keyboard operable and values never rely on color alone. Individual bit cells are pointer-only elements without keyboard semantics or a dedicated screen-reader explanation. The interface is available in 21 languages with a system, light or dark theme; only language and theme are remembered in the browser, and current values cannot be passed on through a link.
