Description

The TFPGreaterThanEqualOperation class implements the greater-than-or-equal comparison operation (>=) between two operands of compatible types. It extends TFPOrderingOperation to provide greater-than-or-equal-specific comparison logic.

The operation compares two values and returns True if the left operand is greater than or equal to the right operand, False otherwise. It handles different data types appropriately, using numeric comparison for numbers, lexicographic comparison for strings, and chronological comparison for date/time values.

This operation combines both equality and greater-than testing, returning True when either condition is satisfied.
