Programmer Converter client-side ?
How to use Programmer ConverterThis converter is built for developers and reverse engineering. Enter a value in the base of your choice — decimal, hexadecimal, octal or binary — and the tool shows all four bases side by side, then reinterprets the value as a signed and unsigned integer over 8, 16, 32 and 64 bits, as float32 and float64 (IEEE-754) and as ASCII text. A little-endian / big-endian switch flips the byte order, essential to decode a memory dump or a network buffer.
Conversions use arbitrary-precision integers (BigInt) and the browser's DataView API for exact results even at 64 bits. Everything is computed locally.

Frequently asked questions
What is the endianness option for?
It flips byte order. Little-endian puts the least-significant byte first (x86, ARM); big-endian is the reverse (network, some file formats).
How do I read a hex value as a float?
Pick the HEX base, enter the value, and read the float32 / float64 lines in the interpretations, adjusting endianness if needed.
