How it is calculated
- Order: brackets, then functions, then ! and %, then powers ^, then × and ÷, then + and −.
- Powers are read right to left: 2^3^2 = 2^9 = 512. And −2^2 = −4.
- x% means x ÷ 100. log is the base-10 logarithm, ln the natural one.
- The text is read by a dedicated parser: no code is ever run.
Example
2 × sin(30) + sqrt(16) ^ 2 in degrees: sin(30) = 0.5, so 2 × 0.5 + 4² = 1 + 16 = 17.
Good to know
- Calculations use floating-point numbers: about 15 exact digits.
- The factorial n! accepts whole numbers from 0 to 170.
- A number like 1,234 is refused because it can be read two ways: write 1.234 or 1234.
