Crate csd 

Canonical Signed Digit (CSD) conversion library.

This library provides functions to convert between decimal numbers and Canonical Signed Digit (CSD) representation.

Features

• multiplier (default): CSD multiplier module for Verilog code generation
• lcsre (default): Longest common substring with repeated elements
• std (optional): Logging support via env_logger

Quick Start

use csd::{to_csd, to_decimal};

// Convert decimal to CSD
let csd = to_csd(28.5, 2);
assert_eq!(csd, "+00-00.+0");

// Convert CSD back to decimal
let value = to_decimal("+00-00.+0");
assert!((value - 28.5).abs() < 1e-10);
