🔒

Local Privacy

Every evaluation runs in your browser. Expressions never leave your device.

How to Use the Scientific Calculator

  1. Choose angle mode: Deg for degrees (sin 30 = 0.5) or Rad for radians.
  2. Tap buttons or type. Example: sin(30), log(100), 2^8, sqrt(16), 5!.
  3. Press = or Enter to evaluate. The result appears in the dark display and is saved as Ans.
  4. Use Ans for chained math, e.g. Ans*2. Click history items to reuse them.
  5. Press AC or Esc to clear, DEL or Backspace to delete one character.
  6. Click Copy Result to copy the current answer.

Understanding Scientific Functions

A scientific calculator extends arithmetic with functions that invert and scale. Sine and cosine project angles onto a circle, logarithms compress powers into exponents, and roots reverse squares and cubes. Knowing which base and angle mode to use avoids the most common errors.

Trigonometry and angle mode

In Deg mode, sin, cos and tan expect degrees, so sin 30 is 0.5 and cos 60 is 0.5. In Rad mode, the same functions expect radians, so sin(pi/2) is 1. Inverses asin, acos, atan do the opposite: Deg returns degrees, Rad returns radians. Switching mode does not re-evaluate past entries. For triangle math see the Percentage Calculator for ratio checks.

Logarithms, powers and roots

log is base 10 (log 100 = 2), ln is base e (ln e = 1). The power operator ^ maps to exponentiation, so 2^8 is 256 and 9^0.5 is 3. sqrt(x) is x^0.5 and cbrt(x) is the cube root. exp(x) is e^x. Factorial ! multiplies integers, so 5! = 120 and 0! = 1.

Constants and Ans

pi and e insert their double-precision values. Ans recalls the last successful result, allowing sequential work like 2+3=5 then Ans*4=20 without retyping.

Honest limitations

Evaluation uses JavaScript double precision. Overflow beyond 1e308 shows Infinity, factorial beyond 170 shows an error, and trig domain errors like asin 2 or log of a negative show an error instead of a complex result. Percent is postfix: 50% is 0.5, and 200*10% is 20.

Privacy and Client-Side Security

Privacy Guarantee: All calculations occur locally inside your browser. Your expressions are never transmitted, stored, or recorded on remote servers.

Many online calculators send every keystroke to a server for evaluation. TinyToolzz keeps everything in-page: parsing and Math operations run with plain JavaScript in the tab.

Because nothing is uploaded, there is no waiting, no account, and no copy of your expressions retained anywhere. They exist only in the tab's memory and are cleared with AC or by closing the page.

Frequently Asked Questions

How do I switch between degrees and radians?
Use the Deg/Rad toggle above the keypad. Deg converts trig inputs as degrees (sin 30 = 0.5). Rad uses radians (sin pi/2 = 1). The label shows the current mode.
What functions are supported?
sin, cos, tan, asin, acos, atan, log (base 10), ln, sqrt, cbrt, pow with ^, exp, factorial !, pi, e, parentheses and percent. Example 2^8 = 256, sqrt(16)=4, 5! = 120.
Can I use the keyboard?
Yes. Type numbers and + - * / ^ ( ) . % directly, Enter for =, Escape for AC, Backspace to delete. The display accepts pasted expressions like sin(30) or log(100).
What is Ans?
Ans holds the last result. After 2+3=5, typing Ans*2 gives 10. It updates after every successful evaluation.
Is my calculation sent to a server?
No. All evaluation runs locally in your browser with JavaScript. Your expressions are never transmitted, stored or logged anywhere. Closing the tab or clicking AC removes them from memory immediately.
How is factorial and log handled?
Factorial ! works for 0-170 integers (5! = 120). log is base 10 (log 100 = 2), ln is natural (ln e = 1). Domain errors like log(-1) or sqrt(-1) show an error.
