Stop Invoice Totals From Drifting by a Yen — Currency Formatting, Consumption Tax, and Rounding in C# with ReoGrid
Hold money in a double and you get rounding error; turn it into a string and totals and sorting break; round consumption tax in the wrong place and your invoice is off by a yen. Money breaks in business apps for predictable reasons. With ReoGrid, cell data stays numeric while it displays as ¥1,234,567 — and reduced-rate (8%/10%) subtotals and invoice-compliant rounding are just formulas.
