The record

Product: uCalc is a C++, C#, and VB parsing and transformation SDK for evaluating expressions and manipulating structured text.
Expression engine: The Fast Math Parser evaluates runtime-defined expressions and supports custom variables, functions, and operators.
Repeated evaluation: The parser supports a parse-once, evaluate-many workflow for repeated calculations.
Text transformation: The Transformer tokenizes text before matching and is designed for code refactoring, linters, and data transpilation.
String library: The String SDK provides mutable, token-aware search and replace, live substring views, and chainable text operations.
Supported environments: The SDK is listed for Windows, macOS, and Linux, with Windows, macOS, and Linux architectures specified on the home page.
Package integration: The maker offers the SDK via NuGet and describes the package as plug-and-play across Windows, Linux, and macOS.
IDE integration: A Visual Studio extension provides token-aware search and transformation inside the IDE.
License limits: SDK license seats apply to developers actively writing code, while compiled products may be distributed royalty-free without platform-count fees.
Preview limitation: The current preview does not yet have all safeguards for untrusted input, and the maker advises against using it to process untrusted input in production.
Legacy apps: The Console Calculator and Transform(er) App have not been updated in over 10 years and do not match the current documentation.
Support: uCalc accepts technical assistance, pricing, and general product inquiries through its contact form, and commercial SDK licenses include 12 months of priority technical support.
Privacy: Code entered in interactive examples and questions sent to the uCalc AI assistant may be shared with third parties and should not contain confidential information.
Company: The maker identifies itself as uCalc Software, a sole proprietorship founded by Daniel Corbier, with a Charlotte, North Carolina address.
