_itoa, _i64toa, _ui64toa, _itow, _i64tow, _ui64tow
Convert an integer to a string.

char *_itoa( int value, char *string, int radix );

char *_i64toa( __int64 value, char *string, int radix );

char * _ui64toa( unsigned _int64 value, char *string, int radix );

wchar_t * _itow( int value, wchar_t *string, int radix );

wchar_t * _i64tow( __int64 value, wchar_t *string, int radix );

wchar_t * _ui64tow( unsigned __int64 value, wchar_t *string, int radix );

Libraries

LIBC.LIB Single thread static library, retail version
LIBCMT.LIB Multithread static library, retail version
MSVCRT.LIB Import library for MSVCRT.DLL, retail version


Return Value

Each of these functions returns a pointer to string. There is no error return.

Parameters

value

Number to be converted

string

String result

radix

Base of value; must be in the range 2 – 36

Remarks

The _itoa, _i64toa, and _ui64toa function convert the digits of the given value argument to a null-terminated character string and stores the result (up to 33 bytes) in string. If radix equals 10 and value is negative, the first character of the stored string is the minus sign ( – ). _itow, _i64tow, and _ui64tow are wide-character versions of _itoa, _i64toa, and _ui64toa respectively.

Example

/* ITOA.C: This program converts integers of various
* sizes to strings in various radixes.
*/

#include <stdlib.h>
#include <stdio.h>

void main( void )
{
  char buffer[20];
  int  i = 3445;
  long l = -344115L;
  unsigned long ul = 1234567890UL;

  _itoa( i, buffer, 10 );
  printf( \"String of integer %d (radix 10): %s\\n\", i, buffer );
  _itoa( i, buffer, 16 );
  printf( \"String of integer %d (radix 16): 0x%s\\n\", i, buffer );
  _itoa( i, buffer, 2  );
  printf( \"String of integer %d (radix 2): %s\\n\", i, buffer );

  _ltoa( l, buffer, 16 );
  printf( \"String of long int %ld (radix 16): 0x%s\\n\", l,
                                                    buffer );

  _ultoa( ul, buffer, 16 );
  printf( \"String of unsigned long %lu (radix 16): 0x%s\\n\", ul,
                                                    buffer );
}


Output

String of integer 3445 (radix 10): 3445
String of integer 3445 (radix 16): 0xd75
String of integer 3445 (radix 2): 110101110101
String of long int -344115 (radix 16): 0xfffabfcd
String of unsigned long 1234567890 (radix 16): 0x499602d2

_ultoa, _ultow
Convert an unsigned long integer to a string.

char *_ultoa( unsigned long value, char *string, int radix );

wchar_t *_ultow( unsigned long value, wchar_t *string, int radix );

Return Value

Parameters

value

Number to be converted

string

String result

radix

Base of value

Remarks

The _ultoa function converts value to a null-terminated character string and stores the result (up to 33 bytes) in string. No overflow checking is performed. radix specifies the base of value; radix must be in the range 2 – 36. _ultow is a wide-character version of _ultoa.

Ok, jeg fik vidst skrevet at det var en unsigned int, det skulle have været en unsigned long - men det fangede i vidst, for _ultoa fungerer perf.

Tak

i = du
