Decimal Calculator — How It Works

A simple four-function calculator for decimal numbers — add, subtract, multiply, or divide.

How it works

Enter two numbers, choose an operation, and get the result.

12.5 + 3.25 = 15.75
12.5 - 3.25 = 9.25
12.5 × 3.25 = 40.625
12.5 ÷ 3.25 = 3.846154

Tips

  • Division by zero is flagged instead of returning an error.
  • Results are shown with up to 6 decimal places of precision.
