About the Formula Calculator
The Formula Calculator evaluates the math formula you type, complete with order of operations, scientific functions, and constants. Great for testing a formula before putting it into code or a spreadsheet.
Like the other calculators in this category, there is no eval/Function — a dedicated parser ensures only math operations run, so it is safe in the browser.
