Crystal Reports lets you use
overflow field representation to assist users who are working with numeric or
currency values in report cells. When the Allow Field Clipping option is not
selected (the default behavior), numeric/currency field values that exceed the
field size are represented by number signs (######) when you preview the
report, letting you know immediately when the field is too small.
Otherwise, if a numeric or currency value
is larger than the field containing it, that value is truncated, or "clipped."
For example, values like 100,000,000 might appear on the report as 1,000, or as
000 (depending on the properties you have set). This could potentially cause
confusion when the report is read.
