ftCurrency

ftCurrency = 7

Example

function IsFourDecimalCurrency(Field: TField): Boolean;
begin
  Result := Field.DataType = ftCurrency;
end;

Usage

ftCurrency identifies Velox's signed fixed-point Currency field with four decimal places and scaled-Int64 range and rounding boundaries.

Additional Technical Info

ftCurrency is declaration ordinal 7 of TFieldType. Delphi Currency is a signed fixed-point value stored as an Int64 scaled by 10,000, giving four decimal places and an approximate range of -922,337,203,685,477.5808 through 922,337,203,685,477.5807.

It provides exact four-decimal arithmetic within range, but does not carry an ISO currency code. Values with more than four fractional digits require an explicit rounding rule; wider precision requires formatted BCD/provider decimal handling. Avoid routing amounts through binary Float or locale-formatted text.

The example only inspects metadata and was source-reviewed; no monetary calculation/dataset/database/runtime/image test ran.
