DECIMAL structure (wtypes.h)

  • Article

Represents a decimal data type that provides a sign and scale for a number (as in coordinates.)

Decimal variables are stored as 96-bit (12-byte) unsigned integers scaled by a variable power of 10. The power of 10 scaling factor specifies the number of digits to the right of the decimal point, and ranges from 0 to 28.

Syntax

typedef struct tagDEC {
  USHORT wReserved;
  union {
    struct {
      BYTE scale;
      BYTE sign;
    } DUMMYSTRUCTNAME;
    USHORT signscale;
  } DUMMYUNIONNAME;
  ULONG  Hi32;
  union {
    struct {
      ULONG Lo32;
      ULONG Mid32;
    } DUMMYSTRUCTNAME2;
    ULONGLONG Lo64;
  } DUMMYUNIONNAME2;
} DECIMAL;
