Floating-Point Data Types
In the realm of Rust programming, understanding how computers handle fractional values is essential. Unlike integers, which deal with whole numbers, floating-point data types are designed specifically for numbers with decimal places. Rust offers two main floating-point data types: 32-bit (single precision) and 64-bit (double precision). Let's dive deeper into the world of floating-point data types and explore their nuances. Floating-point values in Rust are stored in multiple parts, including a fractional value and an exponential value used for scaling. While the 64-bit floating-point data type can represent incredibly large numbers, its precision is finite. This means that even though it can handle huge magnitudes, there's a limit to the number of significant digits or decimal places it can accurately represent. For example, consider the value of PI. As an irrational number with an infinite decimal expansion, representing it as a floating-point value inevitably leads to limita...
