_ltoa

Description

Converts a long integer to a string.

char *_ltoa( long value, char *string, int radix );

Remarks

The _ltoa function converts the digits of value to a null-terminated character string and stores the result (up to 33 bytes) in string. The radix argument specifies the base of value, which must be in the range 2–36. If radix equals 10 and value is negative, the first character of the stored string is the minus sign (–).

Return Value

The _ltoa function returns a pointer to string. There is no error return.

Compatibility

Standards:None

16-Bit:DOS, QWIN, WIN, WIN DLL

32-Bit:DOS32X

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
