Description

TBcd represents a binary coded decimal value. It contains the following fields:

Field 
Contents 
Precision  
The number of digits in the decimal version of the value.  
SignSpecialPlaces  
The sign bit (0 is positive, any other value negative)  
Fraction  
An array of BCD nibbles, 00 to 99 per byte, high nibble first. Only the first Precision nibbles are used.  

You can create a Variant that represents a TBcd value using the VarFMTBcdCreate function. In fact, the easiest way to manipulate TBcd values is to create Variants for them and use the built-in operators provided by the Variant type.
