Here's what's new in the uCalc SDK
Welcome to the most significant update in uCalc's history. The uCalc SDK has been completely overhauled to provide advanced expression parsing and token-aware text transformation. Whether upgrading from a legacy version or discovering uCalc for the first time, this release introduces a modernized architecture, deep language integration (C++, C#, VB), and a brand-new, interactive learning experience.
The best way to learn an SDK is by using it. That is why a massive new documentation hub has been launched, featuring over 600 live, interactive examples. Test string manipulations, math parsing, and code transformations directly in the browser without writing a single line of setup code.
The uCalc SDK is now a unified toolkit featuring three core, seamlessly integrated components:
The Expression Parser: Mathematical and logical evaluation built upon the proven "Parse-Once, Evaluate-Many" architecture from previous versions.
The Transformer: An intelligent, token-aware engine for complex find-and-replace operations (superior to standard RegEx).
The String Library: Robust data cleaning and manipulation.
