# TBCDField.MinValue

Minimum value for the field

## Declaration

Source position: db.pas line 842

`published property TBCDField.MinValue : Currency 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, TBCDField.MaxValue should also be set, because it will also be checked.
