Advanced Calculator with Square Root: Perform Basic Math and Square Root Operations

Use this browser-based calculator to add, subtract, multiply, divide or find square roots in three clicks. Enter two values (e.g., 7.3 and 2.8), pick an operation, press “Calculate,” and the tool returns a result rounded to 4 decimal places. JavaScript uses IEEE 754 double precision, giving up to 15 significant digits—enough for most engineering tasks (IEEE 754-2019).
