// How winecalc works
//
// 1. In the original calculator, numbers are "extended precision".
// We emulate with calcfloat (calcfloat floating point) for now.
// Note that recent M$ compilers 5.0 and later do not implement double float,
// and do not support 80-bit numbers. Max width is 64-bits.
//
// 2. 4 temp areas:
//
// i) current edit buffer value for keystrokes
// ii) computed value area for last computation
// iii) memory area for MR, MC, MS, M+
// iv) formatted display buffer
//
// 3. Memory Store works off current buffer, not value
//
// 4. display limit is 32 numbers plus 10 commas plus one period = 43 characters
//
// 5. original calc is better called SciCalc and saves settings in win.ini:
//
// [SciCalc]
// layout=1 (0 = scientific mode, 1 = basic mode)
// UseSep=1 (0 = no digits separator, 1 = enable digits separator)
//
// 6. Window Menus
//
// The menus know their own states, so we don't need to track them
// When switching to Standard Calculator Mode, number base is changed to Decimal and Trig Mode to Degrees,
// but Word Size Mode is unchanged
//
// 7. It would be nice to add command line parsing for batch files
//
// various display error messages
