About this utility

How to use Safe Math Expression Evaluator

Evaluate arithmetic and common mathematical functions with a purpose-built parser—never JavaScript eval.

What to provide

Use numbers, parentheses, + − × ÷ %, powers, factorials, constants pi/e, and documented functions such as sqrt, sin, cos, log, min, and max.

  1. Paste, type, or drag and drop a supported text file into the input area.
  2. Choose the options that match your intended result.
  3. Select “Run tool” or press Ctrl/Command + Enter, then copy, download, or move the result back into the first input for another pass.

What the result means

Numeric result, normalized expression metadata, and parser diagnostics.

Privacy and safety

This utility is loaded as browser code and processes your input only in this tab. OmniCastConverter has no upload endpoint and never stores your content, filenames, tokens, or secrets. Generated markup and code are shown as inert text and are never executed.

Limitations

  • This is floating-point arithmetic, not a symbolic algebra system, arbitrary-precision decimal library, or unit-aware calculator.
