Formula Blueprint
Trig angle conversion
When degree mode is active, trig inputs convert to radians before evaluation.
radians = degrees × π / 180
Power and root syntax
`^` maps to exponentiation, and roots can be written with `sqrt(x)` or `x^(1/n)`.
xy, sqrt(x), x1 / n
π
3.1415926536
e
2.7182818285
log(x)
Base 10
ln(x)
Natural log
Common Questions
Scientific Calculator FAQs
Short answers for expression syntax, trig behavior, and supported scientific functions.
What is the difference between degree and radian mode?
Degree mode converts trig inputs like `sin(30)` into radians before evaluation. Radian mode uses the numeric input directly, so `sin(pi / 6)` works naturally there.
Does `log()` mean base-10 or natural log?
`log(x)` is base-10 logarithm, while `ln(x)` is natural logarithm.
How do I enter exponents and roots?
Use `^` for powers such as `2^8`, `sqrt(144)` for square roots, or fractional exponents like `81^(1/4)` for higher-order roots.
Why does the calculator reject some text?
The parser only allows a limited scientific syntax. Unsupported text, malformed operators, or unbalanced characters trigger validation instead of being evaluated.
Do results update instantly?
Yes. Results refresh as you type or click a keypad button. No separate calculate flow is required.
How accurate is this calculator?
The engine uses JavaScript's double-precision floating-point arithmetic (IEEE 754). That is high precision for everyday scientific use, but some expressions can show tiny floating-point rounding artifacts (for example, long repeating decimals).
