crunch_eval
High-performance algebraic expression evaluator.
Basic usage:
use crunch_eval::expr::Expr;
let expr = Expr::compile("1 + 1").unwrap();
let val: f64 = expr.evaluate_blank().unwrap();
assert_eq!(val, 2.0);
Benchmarks:
Expression: 6.5*7.8^2.3 + (3.5^3+7/2)^3 -(5*4/(2-3))*4 + 6.5*7.8^2.3 + (3.5^3+7/2)^3 -(5*4/(2-3))*4 + 6.5*7.8^2.3 + (3.5^3+7/2)^3 -(5*4/(2-3))*4 + 6.5*7.8^2.3 + (3.5^3+7/2)^3 -(5*4/(2-3))*4
