TFloatField.MinValue

Minimum value for the field

Declaration

Source position: db.pas line 664

published property TFloatField.MinValue : Double
  read FMinValue
  write FMinValue;

Description

MinValue can be set to a value different from zero, then it is the minimum value for the field. When setting the field's value, the value may not be less than MinValue. Any attempt to write a smaller value as the field's content will result in an exception. By default MinValue equals 0, i.e. any floating-point value is allowed.

If MinValue is set, MaxValue should also be set, because it will also be checked.
