IEEE 754 Float Converter
What is an IEEE 754 Float Converter?
Convert decimal floating-point numbers into 32-bit Single Precision and 64-bit Double Precision IEEE 754 binary bit representations (Sign, Exponent, Mantissa/Fraction), and vice versa.
Why Use This Converter?
- Computer Architecture: Inspect how binary floating-point numbers are represented in memory and CPU registers.
- Debugging Float Imprecision: Understand why `0.1 + 0.2 === 0.30000000000000004` in JavaScript and C.
- Embedded Systems & Game Engines: Decode raw binary float buffers from C/C++ network packets.
How to Use
- Enter a decimal float (e.g. `3.14159`) or 32-bit / 64-bit binary bit string.
- View automatic breakdown into Sign Bit, Exponent Bits, and Mantissa Bits.
- Examine exact stored float value and rounding offset.
Real Conversion Example
Input (TEXT):
0.15625
Output (TEXT):
32-bit Binary: 0 01111100 01000000000000000000000 Sign: 0 (+) Exponent: 01111100 (Decimal 124, Unbiased -3) Mantissa: .01000000000000000000000 (1.25 in binary)
Important Technical Details & Mechanics
- JavaScript ArrayBuffer / DataView: Uses native TypedArrays (`Float32Array`, `Float64Array`) for exact hardware-level bit extraction.
- Special Value Support: Full support for `+0`, `-0`, `+Infinity`, `-Infinity`, and `NaN` bit patterns.
- Local Browser Execution: Instant, hardware-exact calculation.

- URL Encoder: Encode and decode URL parameters.
Frequently Asked Questions
What is IEEE 754 standard?
It is the standard representation for floating-point numbers used by almost all modern CPUs, GPUs, and programming languages.
Why does 0.1 have rounding error in IEEE 754?
0.1 cannot be represented exactly as a finite binary fraction, leading to minor rounding discrepancies in 64-bit floats.
Does it support 64-bit Double Precision?
Yes, both 32-bit Single Precision and 64-bit Double Precision are calculated.
Is it free?
Yes, 100% free with no registration.
What is the main function of IEEE 754 Float Converter?
Convert floating-point numbers to single (32-bit) and double (64-bit) IEEE 754 binary bit patterns, sign, exponent, and mantissa. This converter transforms ieee 754 float data formats locally without server uploads.
