Programmer Base and Bit Workbench is a desktop number-base converter, interactive bit-level register editor, IEEE-754 floating-point layout analyzer, and bitwise expression evaluator for Linux software and systems engineers. An independent graphical alternative inspired by command-line hex2dec and programmer calculator utilities, it supports 8, 16, 32, 64, and 128-bit signed two's complement and unsigned integer representations.

Key Features:

• Multi-Radix & Endianness Workbench: Live synchronized conversion across Hexadecimal, Unsigned Decimal, Signed Two's Complement Decimal, Binary, Octal, and ASCII/UTF-8 bytes with instant Big-Endian / Little-Endian byte swapping, popcount, leading/trailing zero counts, and 8/16/32/64/128-bit width masking.
• Interactive 64-Bit Toggle Grid & Bitwise Evaluator: Clickable 64-bit register matrix paired with an expression engine supporting &, |, ^, ~, <<, >>, rol(), ror(), bswap(), and popcnt() operations.
• IEEE-754 Float32/Float64 & Unix Epoch Inspector: Decomposes single and double precision floats into Sign, Biased/Unbiased Exponent, Mantissa bits, and exact rounding delta alongside a Unix epoch (s/ms/us/ns) to ISO-8601 converter.
• Batch Radix Table & Binary Word Inspector: Converts lists of numbers or reads real 32/64-bit binary words from local files with CSV and JSON export.
