Hello,
i have problem to use Eina convert function, i think im not understand
how that's work.
if someone can explain me please.
so i have a function to make my convertion, but all the time the
convertion failed, but i can't see why.
maybe some on can explian what i m doing wrong, please ?
My code :
------------------------------------------------------------------------------------------------------------------------------------------------
#include <stdlib.h>
#include <stdio.h>
#include <math.h>
#include <Eina.h>
double convert_string_double(const char *tmp) {
long long int m = 0;
long int e = 0;
double r;
//int taille_string = strlen(tmp);
if (!eina_init()) {
printf("Error during the initialization of eina.\n");
return EXIT_FAILURE;
}
printf("value string : %s\n", tmp);
//convert string to double
if (eina_convert_atod(tmp, strlen(tmp), &m, &e))
printf("Convertion Sucess \n");
else
printf("Convertion Failed \n");
r = ldexp((double) m, e);
//printf("value double: %f\n", r);
eina_shutdown();
return r;
}
char *convert_string_kb_to_mo(char *data) {
char *tmp = {0};
double t = 0;
//converti en MO
printf("DATA = %s\n", data);
t = atof(data) / 1000;
printf("T = %f\n", t);
if (!eina_init()) {
printf("Error during the initialization of eina.\n");
// return EXIT_FAILURE;
}
//convert string to double
if (eina_convert_dtoa(t, tmp))
printf("Convertion Sucess \n");
else
printf("Convertion Ratée \n");
return tmp;
}
int main(void) {
char *tmp = "12.5G";
char *tmp2 = "2061672";
char *tmp_final;
double r = 0;
r = convert_string_double(tmp);
tmp_final = convert_string_kb_to_mo(tmp2);
printf("r = %f\n", r);
printf("tmp_final = %s\n", tmp_final);
eina_shutdown();
return EXIT_SUCCESS;
}
------------------------------------------------------------------------------------------------------------------------------------------------
The résult :
------------------------------------------------------------------------------------------------------------------------------------------------
i...@issa-desktop:/media/Element/programmation/EFL/program/Convertion_Eina/bin$
./main
value string : 12.5G
Convertion Failed
DATA = 2061672
T = 2061.672000
ERR: eina_convert.c:528 eina_convert_dtoa() safety check failed: des ==
NULL
Convertion Ratée
r = 0.000000
tmp_final = (null)
------------------------------------------------------------------------------------------------------------------------------------------------
Thanks
