Greg's calculator - a terminal UI calculator inspired by galculator (GTK), implemented in Go with Bubble Tea. Features decimal math, base display cycling (DEC/HEX/BIN/OCT) with CERR on non-integers, tactile keypad, wide integrated display.

Grok a3ed82c6d9 feat(engine): implement core calculation engine (phase 2) ... - float64 decimal math + classic entry buffer (in-progress digits visible) - CycleBase() with IsInteger() (epsilon) + ErrConversionNotPossible (CERR) - FormatForDisplay() for DEC/HEX/BIN/OCT (integer formatting for non-DEC) - Basic ops: + - * / and MOD (math.Mod) - Equals, SetOperator, EnterDigit/DecimalPoint, ClearEntry, AllClear, ChangeSign, Backspace - Comprehensive tests covering the critical CERR path (23/6, 1/3 + BASE) plus arithmetic and MOD This completes the pure engine. The engine is now usable by the upcoming TUI spike. Paper trail updated.		2026-06-06 14:29:36 +01:00
