NumPad
TsgcHTMLComponent_NumPad — a touch numeric and currency keypad built for point-of-sale entry, with quick amount buttons and a hidden field that always posts a locale-independent number, in Delphi, C++ Builder and .NET.
TsgcHTMLComponent_NumPad — a touch numeric and currency keypad built for point-of-sale entry, with quick amount buttons and a hidden field that always posts a locale-independent number, in Delphi, C++ Builder and .NET.
Set Mode and DecimalPlaces, then read the HTML property; the pad posts a number like 12.50 under FieldName, never a locale-formatted 12,50.
TsgcHTMLComponent_NumPad
Calculator-style keypad + display + inline script
Delphi, C++ Builder, .NET
Every number this component writes, into the markup and into its own script, goes through a locale-independent formatter, never through a routine that honours the browser's regional settings.

npInteger (no decimal key at all), npDecimal (default) or npCurrency, prefixed by CurrencySymbol.
Default 2, clamped 0–6. Every value the pad shows or posts is padded/rounded to this many decimals.
A TStrings of tender shortcut numbers; each entry is parsed and re-emitted through the same locale-independent formatter, so a malformed entry is dropped rather than reaching the page.
Hidden field the normalized value posts under, default amount.
0 (default) means no ceiling; above 0, a keystroke that would exceed it is rejected.
Enter becomes a real submit button when either is set, pushing over the sgcHTMX WebSocket bridge or POSTing to Action; a sgc:numpad DOM event always fires.
