C Data Type Definition

typedef struct NUMBER
{
   int length;
   short scale;
   BYTE mantissa[NUMBER_MAX_MANTISSA_SIZE];
} NUMBER;

Usage

The layout of NUMBER is the same as that of the NUMBER data type when transferred to or from the client: a two byte scale followed by the significand. The maximum length is 19.

Here is an example using NUMBER in a UDF definition and C function declaration.
