With various other optimizations, v1.1.3 comes with inner loop optimizations which uses a blazing fast, post-fix style algorithm to quickly evaluate inner brackets with less checks and less string manipulations.

In benchmarks, it beats com.expression.parser(Java Math Expression Parser) by almost (10x-14x) and edges out Exp4J (which is lightweight) in many benchmarks.

It **beats exp4J, and com.expression.parser on evaluation speed** across every kind of expression — from simple algebra to heavy trig, matrices, and calculus; and manages to beat Janino, the gold standard on some, while rivalling it on a host of other expressions

The normal mode routinely does about **3-10 million evaluations per second** while the new Turbo mode easily peaks at about **10 million to 90 million evaluations per second**.
