Floating Point Arithmetic Tool

Lightweight tool for converting and analyzing variable-width floating point numbers during hardware development.

The Problem

Hardware engineers debugging FPUs and datapath components frequently need to convert between floating-point representations. Manual calculation is tedious and error-prone, especially with non-standard bit widths.

Features

• Variable Width Support: Custom bit widths and configurable mantissa/exponent sizes
• Multiple Representations: Binary, hexadecimal, decimal, and scientific notation outputs
• IEEE 754 Formats: Built-in support for standard formats
• Offline Ready: Client-side JavaScript, no server required

Use Cases

• Verify FPU outputs against expected results
• Debug floating-point arithmetic in custom processors
• Analyze precision loss in datapath operations
