This article explores std::numeric_limits in standard C++ and TNumericLimits in Unreal Engine, providing a type-safe alternative to legacy C macros for querying arithmetic type properties.
It covers practical applications including variable initialization, overflow detection, generic programming, and handling special floating-point values like infinity and NaN.
The guide includes working code examples for both standard C++ and Unreal Engine contexts, demonstrating real-world scenarios such as finding minimum/maximum values and implementing safe arithmetic operations.
