Integer & Real Number Comparison Tool
Compare large integers, scientific notation, and math expressions. Features expression parsing and history log.
Comparison History
About
Scientific and engineering contexts often require comparing values across vastly different scales, such as sub-atomic distances (1e-15) versus astronomical distances (1e20). Standard calculators fail when inputs exceed typical integer limits or involve complex expressions mixed with scientific notation.
This tool evaluates mathematical expressions on the fly before comparison. It handles standard operators (+, −, ×, ÷), grouping symbols, and scientific E-notation. It is particularly useful for students checking inequality homework or developers verifying boundary conditions in logic.
Formulas
The tool uses a parsing engine to evaluate the left hand side (LHS) and right hand side (RHS). The logic follows the trichotomy property of real numbers:
