#define RANDOM_MAX 0x7FFFFFFF

char * itoa (int val, char *s, int radix)

char * ltoa (long val, char *s, int radix)

char * utoa (unsigned int val, char *s, int radix)

Conversion functions for double arguments.

Note that these functions are not located in the default library, libc.a, but in the mathematical library, libm.a. So when linking the application, the -lm option needs to be specified. #define DTOSTR_ALWAYS_SIGN 0x01 /* put '+' or ' ' for positives */

#define DTOSTR_PLUS_SIGN 0x02 /* put '+' rather than ' ' */

#define DTOSTR_UPPERCASE 0x04 /* put 'E' rather 'e' */

#define EXIT_SUCCESS 0

#define EXIT_FAILURE 1

char * dtostre (double __val, char *__s, unsigned char __prec, unsigned char __flags)

char * dtostrf (double __val, signed char __width, unsigned char __prec, char *__s)
