Scientific calculator.

A little more power. The same clear thinking.

Let’s work it out

Angles in degrees

Functions

A little less mental math.

15-digit precision. Zero distractions.

Try a little math

More possibilities, without the complexity.

Enter a number, then choose a scientific function. For a power, enter the base, choose xʸ, enter the exponent and press equals. Like the basic calculator, chained operations run left to right; this is not an algebraic expression parser.

Square root81 → √x9

Raise to a power2 → xʸ → 8 → =256

Sine in degrees30 → sin (DEG)0.5

Base 10 logarithm100 → log2

Factorial5 → x!120

Degrees or radians?

Use DEG for angles such as 30°, 45° and 90°. Use RAD when your angle is measured in radians, often as a multiple of π. Click the DEG/RAD control above the scientific keys to switch. The chosen unit affects sin, cos and tan, not arithmetic.

Know the limits.

Square roots require non-negative numbers. Logarithms require positive numbers. Factorial accepts whole numbers from 0 to 170. Powers accept exponents between −10,000 and 10,000; a negative base requires a whole exponent. Results are rounded to 15 significant digits, and complex numbers are not supported.
