Calculator character set
A calculator character set is the system that stores and shows symbols on a calculator. It maps each symbol (like digits, operators, and function names) to a number that the device can read. The same idea applies to small displays: digits use simple segment patterns, while letters and extra symbols need larger patterns or separate codes. Some calculators use their own special codes, while newer models may use common character schemes behind the scenes.
Examples include:
- 7-segment codes for digits 0–9
- 14- or 16-segment patterns for letters and math symbols
- Proprietary codes for keys like sin, cos, √, π
- Internal ASCII-like or Unicode-like mappings on some models
