The calculator built into your operating system usually only covers basic operations, and for everything else (trigonometric functions, number base conversion, a mortgage's compound interest) you end up searching for a different specialized calculator for each task. Bundling the three most searched-for modes into a single tool avoids that back and forth.
Scientific mode: beyond adding and multiplying
Covers trigonometric functions (sine, cosine, tangent), logarithms, powers, roots and the operations a student or technical professional needs beyond basic arithmetic. It's the mode built for physics, math or engineering calculations that don't require specialized software, just a calculator with the right functions on hand.
Programmer mode: thinking in the right number system
Developers constantly work with different number bases (decimal, binary, hexadecimal, octal) and with bitwise operations (AND, OR, XOR, bit shifts) that a normal calculator doesn't offer. This mode lets you enter a value in any base, see its equivalent in the others instantly, and perform bit-level operations directly, without having to do the conversions by hand or reach for a programming language's console for a one-off operation.
Financial mode: mortgages and compound interest without a spreadsheet
Calculating a mortgage's monthly payment, or how much an investment will grow with compound interest over the years, requires specific financial formulas that aren't in a standard calculator. This mode directly solves these common personal finance calculations, with no need to build a spreadsheet with custom formulas for a one-off query.
How to use the calculator
- Choose the mode you need: scientific, programmer or financial.
- Enter the values for the calculation you want to make.
- Get the result instantly, with the relevant conversions or breakdowns depending on the mode.

Why having all three modes together matters
A developer who needs to convert a value to hexadecimal to debug code, and minutes later calculate how much interest their savings will generate, shouldn't have to switch tools or tabs for each task. Having all three modes available in the same place saves that context switch, especially useful when both types of calculation come up in the same work session.
Frequently asked questions
Can I convert between binary, hexadecimal and octal directly? Yes, programmer mode shows the same value across the different bases simultaneously.
What bitwise operations does it include? The common bitwise operations used in programming: AND, OR, XOR and bit shifts, among others.
Does the mortgage calculation include the full monthly payment? Yes, financial mode calculates the payment from the principal, interest rate and term.
Is anything I calculate saved? No, calculations are processed in your browser and aren't stored on any server.
