Float Inspector Calculator
Dissect a float's IEEE-754 representation: sign, exponent, and mantissa. Enter your values, click Calculate, and get the full result with its breakdown — everything is processed on your device, nothing is sent to a server.
All calculations run in your browser. Your data is never sent to our servers.
Example
Example Input

About the Float Inspector Calculator
The Float Inspector shows how a decimal number is stored in IEEE-754 format (32-bit single or 64-bit double): the sign bit, exponent bits (with bias), and mantissa bits, plus its hex and binary value. This explains why some decimals cannot be represented exactly.
Useful for understanding floating-point rounding error, numeric debugging, and teaching binary representation.
FAQ
Is this Float Inspector Calculator accurate?
Yes. It uses standard formulas and runs directly in your browser at full JavaScript precision (plus BigInt/decimal.js for large numbers where needed).
Is my data sent to a server?
No. All calculations happen entirely on your device. No values are sent to or stored on our servers.
