bfloat16 converter

About This Tool

This tool provides a precise software model for converting numbers between standard floating-point formats and the bf16 representation. It targets ML engineers, data scientists, and researchers who need reproducible bf16 encodings for quantization, model testing, and cross-device validation. The system accepts decimal, hex, or binary inputs and can produce outputs in 4-hex, 16-bit binary, and decimal forms. Conceptually, it parses the input value, derives the bf16 bit pattern through sign, exponent, and mantissa handling, then applies rounding per the selected mode to the bf16 mantissa. It handles special values like Inf and NaN according to IEEE 754 rules and surfaces consistent results for validation tasks. The tool distinguishes between required behavior (parsing, conversion, and outputs) and optional features (batch conversions, rounding controls, and special-case notes for subnormals). Its primary value comes from providing a deterministic, auditable path for bf16 encoding decisions in ML pipelines, hardware verification, and model deployment workflows. Use cases include validating quantization fronts, preparing test vectors for bf16 hardware simulators, and ensuring that software representations match hardware expectations. Unique differentiators include explicit rounding mode support, multi-format input, and explicit outputs in both hex and binary alongside a decimal approximation, all with strict IEEE 754 alignment.
