Property of the ScriptLine : BookFormat.
By default, depending on the Size Units used, Q++Studio rounds off Quark document sizes to :
•Centimeters : 2 decimals (eg. 15.75 cm).
•Inches : 4 decimals (eg. 5.8125 inches).
In some cases you may need to have an extra decimal of accuracy. In those cases set this property to true. However, the default precision above is usually more than enough and this property should usually always be set to false (the default value for any new script).
