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)
