About Scientific Calculator

Scientific Calculator is a free browser-based Mycelgrid app for evaluating supported real-number mathematical expressions with scientific functions.

Safe expression evaluation

The app uses a purpose-built tokenizer, parser, and numeric evaluator. Entered expressions are treated as calculator data rather than JavaScript code; the calculator does not use eval or dynamically generated functions to execute the expression.

Browser-local work

Expressions and results are evaluated in the active browser page. Ans, memory, and calculation History exist only in page memory and are cleared when the page is reloaded or closed. No remote math API, account, cloud history, or app-owned recovery service is required.

Number model

The engine uses standard JavaScript Number values, based on IEEE-754 double-precision floating point. It rejects non-finite successful results and applies explicit domain rules for division, logarithms, roots, powers, factorials, and tangent singularities.

Scope and limitations

This is a real-number scientific calculator, not a graphing calculator, symbolic algebra system, arbitrary-precision engine, complex-number calculator, statistics suite, or certification for exams, engineering, scientific, financial, medical, or safety-critical work.

Privacy, data and limits

Scientific Calculator evaluates the expression you enter in this browser page. It does not upload calculator expressions or results to Mycelgrid for calculation and does not maintain an app-owned account, cloud history or recovery service. Ans, memory and calculation history exist only for the current page session and are cleared when the page is reloaded or closed.

Calculations use standard browser double-precision floating-point arithmetic. Some decimal values and transcendental functions are necessarily approximate, and displayed results may be rounded. This calculator evaluates supported real-number expressions only; it is not a symbolic algebra system, arbitrary-precision engine, graphing calculator, complex-number calculator, or certification for exams, engineering, scientific or safety-critical work.
