single-header, type-safe, generic dynamic array library for C
/**
* stb_vector.h - v1.0 - public domain type-safe generic dynamic arrays
*
* This is a single-header-file library that provides easy-to-use
* dynamic arrays for C (also works in C++).
*
* DO THIS ONCE, AT THE START OF ONE SOURCE FILE:
* #define STB_VECTOR_IMPLEMENTATION
* #include "stb_vector.h"

A C++17 tool convertes hexadecima into floating-point numbers. It features functions for parsing input, swapping byte order, and converting to float. The code emphasizes clarity, efficiency, and robust error handling to ensure reliable performance. Was actually derived from https://gregstoll.com/~gregstoll/floattohex/
