Real, float, packed decimal, numeric and Sybase-decimal

Open ClientConnect supports the following five decimal types:

CS_REAL, a 4-byte decimal value.
CS_FLOAT, an 8-byte decimal value.
CS_PACKED370, which is used to handle IBM S/370 packed decimal data. It can be converted to the Adaptive Server money, char, numeric, or Sybase-decimal datatype with cs_convert.

CS_PACKED370 values can be negative. The maximum number of decimal places for a packed decimal object is 31.

CS_NUMERIC, which is used to handle Adaptive Server numeric data. It can be converted to character or packed decimal. For example:

typedef struct _cs_numeric

     CS_BYTE  precision;

     CS_BYTE  scale;

     CS_BYTE  array CS_MAX_NAMELEN;

 } CS_NUMERIC;

CS_DECIMAL, which is used to handle Adaptive Server numeric data. It can be converted to character or packed decimal. It is defined the same way as CS_NUMERIC.
