Detailed Description

An extension to the number formatter. It will strip out the characters '%$,' when parsing a string and can scale values by setting a pattern like (/1024=)0.00 KB which will divide the actual value by 1024 or (*60;4=)0.00 which will multiply the actual value by 60. When used for parsing, the resulting value will be scaled to a scale of 4. So when the real value is 0.0165, the display value will be 0.99 and when this is re-entered, the resulting value will again be 0.0165.
