Rust for Python Programmers #3 — Numeric Types!

<p>Welcome back, intrepid learners! In this exciting part of our Rust journey for Python programmers, we&rsquo;re diving deep into numeric types. We&rsquo;ll explore the available types, operations, and conversions in both Python and Rust, shedding light on Rust&rsquo;s unique concepts along the way.</p> <h1>Available Numeric Types</h1> <h1>Python</h1> <p>Python offers basically 3 kinds of built-in numeric types:</p> <ul> <li><code>int</code>: represents signed integers of arbitrary precision.</li> <li><code>float</code>: represents floating-point numbers, following the IEEE 754 standard.</li> <li><code>complex</code>: represents complex numbers with real and imaginary parts.</li> </ul> <h1>Rust</h1> <p>Rust also provides several numeric types:</p> <ul> <li><code>i32</code>&nbsp;and&nbsp;<code>i64</code>: Signed 32-bit and 64-bit integers.</li> <li><code>u32</code>&nbsp;and&nbsp;<code>u64</code>: Unsigned 32-bit and 64-bit integers.</li> <li><code>f32</code>&nbsp;and&nbsp;<code>f64</code>: Floating-point numbers, akin to Python&#39;s&nbsp;<code>float</code>.</li> <li><code>complex</code>&nbsp;(using external crates): Rust does not have a built-in complex type, but libraries like&nbsp;<code>num-complex</code>&nbsp;can be used.</li> </ul> <h1>Signed and Unsigned Numbers</h1> <p>In Rust, the distinction between signed and unsigned integers is essential. Signed integers (like&nbsp;<code>i32</code>) can represent both positive and negative values, while unsigned integers (like&nbsp;<code>u32</code>) represent only non-negative values. This distinction ensures memory safety and reduces common programming errors.</p> <p>On the other hand, in Python, all integers are represented as signed integers. This means that they can represent both positive and negative values, and there&rsquo;s no separate type for representing only non-negative values, as is the case with unsigned integers.</p> <p><a href="https://medium.com/@julianofischer/rust-for-python-programmers-3-numeric-types-4de871f51ba6">Visit Now</a></p>
