widesquare
Wide square operation. This module provides the WideSquare trait which enables squaring operations that return a result type with double the bit width of the input type. This is particularly useful when you need to square a number without worrying about overflow, as the result type can hold the full range of possible values. # Examples
use core::num::traits::WideSquare;
// Squaring a `u8` value to get a `u16` result
let a: u8 = 200;
let result: u16 = a.wide_square();
assert!(result == 40000);
// Squaring a `u128` value to get a `u256` result
let x: u128 = 0xffffffffffffffffffffffffffffffff; // max u128
let wide_result: u256 = x.wide_square(); // No overflow occurs
assert!(wide_result == 0xfffffffffffffffffffffffffffffffe00000000000000000000000000000001);
Available Implementations The trait is implemented for the following type pairs: - i8 → i16 - i16 → i32 - i32 → i64 - i64 → i128 - u8 → u16 - u16 → u32 - u32 → u64 - u64 → u128 - u128 → u256 - u256 → u512
