Lazarus Calculator

Lazarus Calculator is a handy desktop tool that helps you see the results of basic math operations. It lets you do sums, subtractions, multiplications, divisions, and even find square roots. Plus, you can save a number to memory!

Easy-to-Use Interface

This application is super simple and was created using the Lazarus IDE. You can easily perform calculations with decimal numbers. While it handles basic math like a champ, remember—it can only do one operation at a time.

Calculate Big Numbers

Just like your regular desk calculator, Lazarus Calculator can handle lots of operations with large sets of numbers. It works with up to fifteen digits and fourteen decimals! You can quickly add, subtract, multiply, or divide.

Square Roots and Percentages

You can also estimate the square root of any number or calculate percentages. Need to divide 1 by the number currently on display? No problem! You can easily click the buttons in the interface or use your keyboard for commands.

Memory Features

The calculator has some cool memory options too! Look for the MC, MR, MS, and MP symbols on the left side of the window:

• MP: Adds your current value to memory.


• MS: Saves what's in memory.


• MR: Recalls that value onto your screen.


• MC: Clears out memory completely.

If you want an easy way to estimate results for simple math problems—like sums or divisions—Lazarus Calculator is your best bet! It’s lightweight and takes up less space than Windows’ built-in calculator but supports larger numbers. Don’t forget about those handy memory options and other features like estimating square roots and percentages!
