Hex to Float Converter

Decode IEEE-754 float values from hex for firmware payloads, memory dumps, and protocol analysis.

Open converter

Use the full IEEE-754 tool for float32/float64, endian switching, and field-level decoding.

Example hex values

3F800000 → 1.0 (float32)

BF800000 → -1.0 (float32)

3FF0000000000000 → 1.0 (float64)

Why endian matters

Byte order changes how hex bytes map to IEEE-754 bits. Always match protocol endianness.
