TFloatToDateTimeNode class
Internally used class for converting float to datetime
Declaration
TFloatToDateTimeNode = class(TFPConvertNode)Inheritance

- TObject
Description
The TFloatToDateTimeNode conversion node class handles the conversion of floating-point values to date/time values in expressions.
It supports the standard Pascal datetime representation where the integer part represents days and the fractional part represents time.
The class enables precise datetime calculations by allowing floating-point values to represent both date and time components in a single numeric value. This is particularly useful for calculations involving time intervals and fractional days.
This class is used internally by the TFPExpressionParser class to construct an AST (Abstract Syntax Tree). There is normally no need for you to use or instantiate this class directly.
