Integers and Floating-Point Numbers in C++

Short summary

Master C++ primitive data types including signed/unsigned integers, fixed-width integer types from <cstdint> (int8_t to int64_t), floating-point types (float and double), booleans, and characters. Includes practical code examples showing type declarations and the significance of suffixes like F for float and U for unsigned. Essential reference for C++ developers and those transitioning from Rust or other languages.

• •Fixed-width integer types provide explicit control over bit-width and signedness across platforms
• •Use F suffix for float literals, U suffix for unsigned—Rust-style naming (f32/f64) not available in C++
• •Char is preferred over int8_t for single characters to communicate intent, even though internally they're similar
