ltoa(), lltoa()
Convert a long integer into a string, using a given base
Synopsis:
#include <stdlib.h> char* ltoa( long value, char* buffer, int radix ); char* lltoa( long long value, char* buffer, int radix );
Arguments:
- value
- The value to convert into a string.
- buffer
- A buffer in which the function stores the string. The size of the buffer must be at least 33 bytes when converting values in base 2 (binary).
- radix
- The base to use when converting the number.
This value must be in the range:
2 ≤ radix ≤ 36If the value of radix is 10, and value is negative, then a minus sign is prepended to the result.
Library:
libc
Use the -l c option to qcc to link against this library. This library is usually included automatically.
Description:
The ltoa() and lltoa() functions convert the given long integer value into the equivalent string in base radix notation, storing the result in the character array pointed to by buffer. A NUL character is appended to the result.
Returns:
A pointer to the result.
Examples:
#include <stdio.h>
#include <stdlib.h>
void print_value( long value )
{
int base;
char buffer[33];
for( base = 2; base <= 16; base = base + 2 ) {
printf( "%2d %s\n", base,
ltoa( value, buffer, base ) );
}
}
int main( void )
{
print_value( 12765 );
return EXIT_SUCCESS;
}
produces the output:
2 11000111011101 4 3013131 6 135033 8 30735 10 12765 12 7479 14 491b 16 31dd
