Specifies numeric parsing information.

Syntax

typedef struct {
  INT   cDig;
  ULONG dwInFlags;
  ULONG dwOutFlags;
  INT   cchUsed;
  INT   nBaseShift;
  INT   nPwr10;
} NUMPARSE;

Members

cDig

On input, the size of the array. On output, the number of items written to the rgbDig array.

dwInFlags

Input flags.

NUMPRS_CURRENCY (0x0400)

NUMPRS_DECIMAL (0x0100)

NUMPRS_EXPONENT (0x0800)

NUMPRS_HEX_OCT (0x0040)

NUMPRS_LEADING_MINUS (0x0100)

NUMPRS_LEADING_PLUS (0x0004)

NUMPRS_LEADING_WHITE (0x0001)

NUMPRS_PARENS (0x0080)

NUMPRS_STD (0x1FFF)

NUMPRS_THOUSANDS (0x0200)

NUMPRS_TRAILING_MINUS (0x0020)

NUMPRS_TRAILING_PLUS (0x0008)

NUMPRS_TRAILING_WHITE (0x0002)

NUMPRS_USE_ALL (0x1000)

dwOutFlags

Output flags. Includes all the values for dwInFlags, plus the following values.

NUMPRS_INEXACT (0x20000)

NUMPRS_NEG (0x10000)

cchUsed

Receives the number of characters (from the beginning of the string) that were successfully parsed.

nBaseShift

The number of bits per digit (3 or 4 for octal and hexadecimal numbers, and zero for decimal).

nPwr10

The decimal point position.

Remarks

The following apply only to decimal numbers:

nPwr10 sets the decimal point position by giving the power of 10 of the least significant digit.
If the number is negative, NUMPRS_NEG will be set in dwOutFlags.
If there are more non-zero decimal digits than will fit into the digit array, the NUMPRS_INEXACT flag will be set.
