//! Mathypad Core - Shared calculation and parsing logic
//!
//! This crate contains the core mathematical evaluation, unit conversion,
//! and expression parsing logic that is shared between the TUI and web UI versions of Mathypad.

pub mod units;

// Constants used throughout the application
pub const MAX_INTEGER_FOR_FORMATTING: f64 = 1e15;
pub const FLOAT_EPSILON: f64 = f64::EPSILON;

// Re-export commonly used types for convenience
pub use expression::{
    evaluator::{evaluate_expression_with_context, evaluate_with_variables},
    parser::*,
